L298N dual full-bridge motor driver

Two years ago, I designed my own motor driver breakout board using two L298N motor driver ICs and had them manufactured through BatchPCB. Here it is, finally finished. The KiCAD files are on my github repo here.

LSM303DLM Breakout

Sensors are cool, but the really cool ones come in tiny packages that require breakout boards to be easily usable. I often buy (populated) breakout boards from one of the many hobby electronics vendors out there, but they are often in the $20 to $60 range (like this LSM303 breakout board), which is rather prohibitive.

DIY PCB Etching: Test Run

I found some one-sided blank PCBs on eBay. They are only half as thick (0.0225″) as the ones found in most electronic devices, but I don’t need much more yet. I cut the board by gouging out one side of a small rectangular area with an exacto knife until it was thin enough to be […]
