Bus Pirate Arduino Shield free PCB build
Andrew built a Bus Pirate Arduino Shield from a free PCB. This board gives the Arduino the same front-end circuity as the Bus Pirate. 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 free PCB […]
Android Accessory Development kit free PCB build
Mikelelere built a free Android Accessory Development kit PCB. I’ve assembled over the weekend a free PCB I received last week: the Android Open Accessory Kit. When I ordered this PCB from the free PCB drawer I noticed a paragraph that indicated that the PIC footprint was the wrong size (the pitch was too large […]
DP6037 SMT.v1 free PCB build
Cosminnci posted pictures of his free DP6037_SMT.v1 PCB build. This is a universal breakout board for SOIC microcontrollers. It features a USB power supply and data lines, a quartz crystal, breakouts for all the pins and a small prototyping area. This board was really fun to build, I wanted to get a PIC18F2550 breakout board, but […]
PCB assembly tips: the making of the AASaver
Last March Ray presented his design of a portable breadboard power supply with a selectable voltage using the Microchip MCP1640 boost converter he dubbed the AASaver. After receiving and assembling batches of AASaver PCBs he wrote this tutorial explaining the techniques he uses to manually assemble the boards into a finished, functional product. This is […]

ATX Breakout board free PCB build
Cosminnci built an ATX Breakout board v1.0 free PCB. The ATX breakout board routes the -12, 3.3, 5 and 12 volt ATX outputs to screw terminals, each protected by a 1.25 amp resettable polyfuse. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – […]
Logic Shrimp v2b free PCB build
Mikelelere built a free Logic Shrimp v2b PCB. This board uses a single 23LC1024 SRAM to capture data on 4 inputs. The current v1 uses four 23K256s with each recording a single channel. Aerial data lines (SD0 – SD3) are now bi-directional as well. If you build a free PCB we’ll send you another one! […]
Paddle Clock free PCB build
Faultykyle built one module of the Paddle Clock, a clock kit project we worked on several years ago. The board consists of two 7-segment displays driven via tw0 ‘595 serial to parallel shift registers. The control and serial signals are routed to a PCB edge connecter, which was intended to to plug into the Paddle […]
Quartz crystal breakout
Markus really liked the NU-XTAL quartz crystal breakout board, so he decided to build his own. He had one of our QFP protoboards laying around which had a small quartz crystal breakout on them. He cut it out, hot-glued, and soldered the pins. I like your idea of a plug-and-play XTAL solution for breadboarding. I […]

LogicBoost 6 Channel Logic Analyzer free PCB build
Markus built a free LogicBoost 6 Channel Logic Analyzer PCB: I too got my free PCB on Friday (thanks a lot!) and built it over the weekend. I made a quick proto board containing the MSP430G2553 to free up my LaunchPad for other things. If you build a free PCB we’ll send you another one! […]
LogicBoost 6 Channel Logic Analyzer free PCB build
Hlipka blogged about his free LogicBoost 6 Channel Logic Analyzer PCB build: Thanks to the FreePCB drawer, I got my hands on a LogicBoost board. I got it build up last weekend, and after discovering that I need to swap RX and TX on my launchpad it worked without problems (it’s a 1.3 version which […]
Part Ninja v1 free PCB build
Mikelelere built a free Part Ninja v1 PCB. The Part Ninja is a electronic component testing tool. It identifies electronic components like transistors and FETs, determines the pinout, and measures basic specifications. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send […]
