Luddite 2

ANSI 60% on a Pro Micro

Second version of the Luddite. Fits fine in a cheap plastic case. Or can be assembled with a second PCB as a base like the first version.

The circuit is the same as the first version, some components were moved to avoid the stabilizers.

Gerber file on github. Firmware.

I made a PCB plate for the Luddite here.

Top of the assembled PCB. Diodes and resistors.

Bottom of the assembled board. Mini USB connector, 24pin socket, and MOSFET for LEDs. The tiny ESD protection chip is just below the mini USB connector.

Closeup of the USB connector. The 4 pads are for the pigtail to connect to the Pro Micro, in the same way as the GNAP!
