FreeLSS Electronics Board

This is a small Raspberry Pi 'shield' for controlling a FreeLSS based 3D scanner.

The board measures just 42x52mm, and mounts directly on the Raspberry Pi GPIO port. It has an on board buck converter module which powers the stepper driver (Pololu-style DRV8825 or DRV8832) and also the Rasppberry Pi, so all you need is a single 12-24V plug pack.

I have had enough interest in the PCB's that I have ordered a second batch. Send me a message if you are interested in getting hold of one!

Assembly is pretty straight forward, all components are marked on the board. The only catch is the two MosFETs, check the pinout of the part you are using and make sure you put it in the right way round, the VN10LP for example has the pins the other way round to the outline marked on the board.

Make sure you adjust your DC-DC converter before attaching the board to the Raspberry Pi, you want your 5V output s
