MMA7455L accelerometer free PCB build
Tayken built a free MMA7455L accelerometer breakout board. The MMA7455L is a 3-axis accelerometer with I2C and SPI interfaces. As I finally had my accelerometer, I’ve decided to solder it up using electric skillet method. I thought I had the required tantalum caps so I didn’t order but it turns out I have a different […]
Microchip TQFP-100 breakout board tested
We recently received our Microchip TQFP-100 breakout boards. We tested them with PIC24F and dsPIC33 chips and a “Blink LED” demo firmware. Both chips worked fine. These boards are intended to be breakouts for all Microchip devices that come in TQFP-100 packages (0.4mm pitch, designation PT). These include the PIC24, dsPIC33, and PIC32 families of […]
Bus Pirate v4 LCD adapter free PCB build
BrentBXR posted a picture of his free Bus Pirate v4 LCD adapter PCB build. The LCD adapter lets you test HD44780 comparable LCDs without any extra parts. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the […]
Atmega8 based thermometer build
Andrianakis Haris writes: This is a thermometer I designed for my room, built in a small pack and easy to control. Some basic components used: Atmega8, LM35 for inside temp sensing and DHT-11 for outside temp & humidity sensing. The hardware is designed on a way so that the PCB can be wall mounted. At […]
Infrared thermopile sensor TMP006 breakout free PCB build
Pietja posted pictures of his free Infrared thermopile sensor TMP006 breakout board build. This is a non-contact temperature sensor from TI, we looked at the dev board previously. Unlike us, Pietja successfully soldered both boards. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever […]
AVR transistor tester build
Alan Garfield at fromorbit writes: Hey guys, I built up that AVR Transistor Tester that’s been bouncing around on your site for a few weeks. Thought you might like to see it. I’ve done this short video showing it in operation and also written up a few of the misadventures I had while building it. […]
xQFP protoboard free PCB build
Juan used his free 0.50mm Dangerous xQFP protoboard to get started with a MSP430F5510. The protoboard is designed to get you up and running with a new surface mount microcontroller. We’re super proud of this board, it’s something we use all the time to develop our own projects. Currently available in 0.50mm, 0.65mm, and 0.80mm for […]

RFID breakout board for the Bus Pirate built
Here’s the completed Near Field Communication (NFC) board designed by titanmkd. It uses the TRF7970A IC to read RFIDs from the Bus Pirate and other devices, we wrote about it earlier. All the systems check out OK so far. The next step is to communicate with an RFID card. Via the forum.
LED Christmas card revisited
Drew found our old X-mas card project and decided to build it. Since this project is no longer in production he got a batch of PCBs made by Seeed. The PCB arrived two days ago. We hope he has luck building them before X-mas. Via the contact form.
Lattice CPLD Dev Board free PCB built
Garrett built a free Lattice CPLD breakout board. He documented his soldering technique with pictures. The Lattice CPLD breakout uses the LC4032 CPLD that comes in the low pitch TQFP 44 pin package. Our breakout board allows you to get started without designing a custom board for your chip. If you build a free PCB we’ll […]
Bus Pirate development week – day 1
This week is dedicated to Bus Pirate development. We’re cleaning up firmware v6 and getting ready for a final release. Today we documented the development process to help any prospective developers find their way around the Bus Pirate source. In the video: Compile the Bus Pirate firmware Basic work with SVN Soldering a demo board […]
