LARS V2

This is the second iteration of the hardware. The principle is the same as for the prototype, with the same chinese modules used. Only the buttons have been changed, and there are now 9 of them, with 8 LEDs. The battery is now mounted on the board. It is planned to be used without a case.

You can download the Gerber files to order PCBs online.

Bill of Materials

These are all the parts required to assemble the V2 PCB.
