Currently I have one built on a weird protoboard I bought from RadioShack. Then for the Photon 3. Well this circuit works as it should but I have a feeling it won’t be great as a stand alone setup. I managed to get it working on an Arduino also although I think I toasted the Arduino because it won’t work anymore. Which is weird because my oscilloscope still shows a data waveform but no LEDs are lighting up when instructed. Anyways, all this fussing about with this clunky board has led me to develop a PCB in which I want to have made.

Board Overview. Take a look at the schematic, and you will notice that the breakout board consists of a shunt resistor (R S), the INA chip, and an output resistor (R L).While R S and R L might appear to have 2 resistors, only one is populated on the board. If you would like to change the values of the resistors, you can replace them or put another resistor in parallel.
So I created this small board to change that. On the board there is a USB to serial converter, an 3,3V Voltage regulator and some small circuit to enter programm mode and reset. The PCB has one layer for easy etching at home. The program-mode and reset circuit is based on a circuit by Baoshi see links. Experimenting with the previous setup on a breadboard was no pleassure. The main benefit of this PCB is a much better acces to the program-mode and the reset over one switch.
Circuit The circuit is nothing special: The USB is also used for Power. On the web I found som circuit link to reach this.
Introduction Front side Here is a product whose origin lies in the pain and suffering of an actual development project. Imagine you have a shiny new display made somewhere out there in a world that comes with a demo board and some datasheets. So you take a display, hook it up to your favorite development board and try to follow the documentation.
And yet a a demo next to you works well, but is very tiny, has no test points and not documented.
Breakout Boards. Breakout boards are a common electrical components that take a bundled cable and breaks out each conductor to a terminal that can easily accept a hook-up wire for distribution to .
Rating Excellent GPS module. I’m using it to synchronise the clock on a Raspberry PI. Small and very quick. Just a small thing — I found that the first fix after firing it up for the first time took a VERY long time about 20 minutes. Since then, it acquires a fix very quickly on powerup about 15 seconds and updates quickly and accurately. My search for the ideal GPS module is over. Will definitely buy another. Did find when using theAdafruit GPS library that the notes in the library do not recommend using any higher than 1Hz.
I tried Hhz with a mega and it has been ok so far. I ordered the item and you delivered it.. I am yet to use it Its not like a ham sandwich or a coffee, I cant rate it out of Core Electronics staff – thanks Laurens! Glad to hear your product arrived and hopefully you can let us know how you get on with this product when you get a chance:
nRF Breakout Board Hookup Guide : nRF52
You can download the newest version of the arduino software here. Earlier this year we did an article on using the 74hc shift register with your arduino. It has been, by far, our most popular article. It seems that a lot of people want to control a lot more LEDs or other than the arduino can do without help. And so we came up with the 74hc breakout board. Using right-angle headers you can chain a ton of these together.
Suggested Reading The nRF Breakout is an intermediate-to-advanced level board, but don’t let that scare you off! This tutorial should be able to walk you through getting started with the board regardless of your skill.
They are a common item in electronic projects and enable easy, clean installation of electronic devices. The image at right shows a simple DB25 breakout circuit board from Winford Engineering. The breakout board is positioned between your computer or indexer and the motor drivers and serves two purposes in the CNC control system: Your wiring schematic would look something like the following: The illustration above shows a block diagram for a stepper motor CNC control system. At right we will see four conductors between the driver and the motor.
These wires correspond to the coils inside the motor that are energized to coordinate rotation. Remember, there would be six wires for each stepper if you had unipolar motors and you could have as many as eight wires. For a more information on motors, please click here. Inside the controller box, we see a direction signal and a step signal being distributed from the breakout cirrus board to each driver.
A common ground line is distributed in the same fashion. A power source also distributes power to each driver. Note that there is no power to the board in this system. At left, there are three signal pairs coming from the computer, one for each stepper, and a ground line for the return as indicated by the small black line under the three pairs of signal wires.

Unlike unipolar steppers, bipolar steppers have no common center connection. They have two independent sets of coils instead. You can distinguish them from unipolar steppers by measuring the resistance between the wires. You should find two pairs of wires with equal resistance.
INA Breakout Board Hookup Guide Take a look at the schematic, and you will notice that the breakout board consists of a shunt resistor (R), the INA chip, and an output resistor (R). While R and R might appear to have 2 resistors, only one is populated on .
March 5, For all of our different AVR microcontroller based projects, we seem to find ourselves continually wiring up minimalist target boards ; little circuit boards that fit both the AVR and a 6-pin header for connecting to your in-system programmer. The Design Here is what we ended up with: It is designed so that all of the copper traces are on the bottom side, meaning that it can be built single-sided, either to keep the cost down, or to make it an easy design to fabricate yourself if you like to etch your own boards.
On the top side of the board, dominating the playing field, is the place for the microcontroller, which can sit in a standard DIP socket. All 28 pins of the microcontroller are labeled with their main functions. Besides the pins that actually connect to the ATmega , there are three-count-em-three extra access holes connected to every pin of the microcontroller. In the upper left, there are input connections for power typically V and ground, which are routed to a couple of other locations on the board.
In the upper right is a place for the 6-pin ISP header with pin 1 marked.
IO68 Breakout Module
That means i can can now hookup everything at once, finish the alarm clock software and publish the lot. More details to follow After studying the schematics and DS pinout, I made a breadboard sketch in Fritzing, tried it out and transferred the design to a small piece of stripboard.
This breakout board, based on the best-of-class Si, is an all-in-one stereo audio FM transmitter that can also transmit RDS/RBDS data! Wire up to your favorite microcontroller (we suggest an Arduino) to the I2C data lines to set the transmit frequency and play line .
Clicking this link will create a new Digi-Key cart containing the parts for the board except for the hookup wire, machine screws, and nuts. Design Notes The main body of the circuit is quite simple; the power and ground rails from the Molex connectors are connected directly to the screw terminals along the sides.
In order to achieve high current capacities, the main paths are large power planes. In addition, short pieces of 12AWG copper wire are soldered between the pads marked JP1-JP3 on the bottom see image and JP4 on the top to increase the capacity in places where the board copper alone might be inadequate. This makes some of the solder joints difficult, because the large power planes and fat copper wires tend to conduct heat away from the solder joints they are connected to.
In the end the board didn’t produce as much heat as I had feared, so it might be possible to redesign it to carry all the current in the board’s copper without using the extra 12AWG wires. Only the three main rails are exposed via screw terminals, but all six rails are exposed via the pin header, each with a 1. Projects that don’t need much power can use the fused rails to provide a measure of protection against short circuits. In practice most power supplies use a 5. Otherwise, the P1 and P2 pads can be left unconnected.
Do this at your own risk! See this detailed discussion for more information. There is a mounting hole at each corner of the square. Each hole is 3.

One of Tweak’s jungles of cables, in fact, one of the more orderly ones. Putting together a home studio requires a mind that can visualize, in a second, the signal flow of the entire studio from every remote piece though interfaces, patch bays, mixers, your computer and then the seemingly thousands of virtual cables and switches inside each computer application.
To become the master of your recording studio, whether it is large or small, you must always know where your signal is and know how to get it where you need it to your recorder, most of the time. We connect signals to pieces of gear with cables. To maintain the integrity of the signal, we need to understand which cables to use to connect our gear.

You can also download my Bluegiga Eagle library here. The next major missing piece of Keyglove functionality is wireless support. This involves a battery, charging circuit, and a Bluetooth device. Because I like learning new things and being able to create stuff that is exactly the way I want it, I decided to build a custom breakout board for the module.
Rather than wait for something else to become available, I decided to go for it myself to see what I could come up with. Therefore, a couple of weeks ago I gave myself a crash course in Eagle, which involved a lot of Googling, experimenting, trial and error, and some much-appreciated help from laen and the Wayne and Layne guys. The result was this design, which I was thoroughly proud of and very excited to send in for fabrication: The board is about the same width and slightly shorter than the BP board Wayne and Layne created for me.
It has all of the pins accessible in standard 0. Thanks to the Dorkbot PCB service run by the aforementioned laen along with his speedy work and clever panel arrangement , I was able to get the design sent in for production mere hours after finishing it. I wasted no time at all in mounting the WT12 module on it, which resulted in this beautiful thing: I tried instead melting just a bit of solder on each of the SMD pads on the breakout board, then setting the WT12 module on top and heating the whole thing up with a hot-air rework station until the module basically sunk into place.
Dr. Monk’s DIY Electronics Blog: New Arduino Library for Sparkfun Si FM Receiver Breakout Board
Capable of 27 colour combinations and controllable from either a GUI or the command line, it can also perform patterns. Small board which connects directly to the GPIO header, Light up your case to suit your mood or display status information. The board has been designed to fit directly on top of the RaspberryPi similar to the HAT physical specification. Also available as a bare PCB – ideal for school projects and anyone wanting the extra challenge of soldering some hardware for their Raspberry Pi.
The kit includes a pre-prepared strip-board, all the necessary components and cables, and a very complete full-colour manual with lots of code examples.
This hookup guide is not only limited to the MOSFET breakout board, here you can learn basics of MOSFET, so that you can build your own circuit in a breadboard/ Protoboard with components we are providing or use if you have some with you.
I decided to go with a company I trust, Adafruit Industries, and see what their offering is like. I was not paid or compensated by Adafruit, I purchased this product. Assembly With Adafruit products you can expect a few things: It gives you more freedom with how you set up your boards, and it forces you to get good at soldering. This kit comes to you looking like this: I generally like to place them in the breadboard when soldering to keep everything straight.
Some have warned against this because you might damage your breadboard.
DIY Motor Drivers Stepper Drivers Driving a stepper motor is unfortunately not as simple as a DC motor, the bipolar motors I used have two windings that you energise in a certain order to make the motor move one step. CNC software however sends just two signals, step and direction, so to interface the stepper motors with the parallel port you need to make some drivers. Version 1 of my drivers I decided to design and make myself, mainly to practice my PCB manufacturing skills, I would only recommend making your own boards if you really want the full home made experience because they do not run as well as purchased drivers and in the end they didn’t even turn out to be cheaper good experience though.
After a lot of research it seemed the easiest driver chips about for bipolar stepper motors are the L and L N, these allow you to drive steppers up to 36V 2A per winding and allow half-stepping which will double your resolution. The circuit is even nicely provided in the L N datasheet, you can sink multiple boards together to use the same clock source which is meant to ensure that each board runs at the same speed this didn’t seem to work for me, I blame noise due to my dodgy PCB manufacture.
Just because the stripes are in a certain order doesn’t mean the resistor has a direction! Resistors are the same forward and backwards, it doesnt matter which way they are used. Highlight the text below to see the answer Red – Red – Brown – Gold What is the value of this resistor? Highlight the text below to see the answer Ha! Trick question, it is not possible to put a resistor in ‘backwards’. They work either way! Say hello to the LED! We’ve had some time with the LED already, but lets get to know her a little better.
The light-emitting part, well, that makes sense. We’ve used the LED to make a blinking light in lessons 1 and 2. The LED component turns current into light, much like any sort of light bulb.
