HARDWARE:

An Eagle 6 board layout file and BOM are included in the pcb/ folder. There is also a design for a "programming cradle" that mates the test points on the UMR2 with a PIC programmer.

A public CircuitHub project is available for on-demand manufacturing: https://circuithub.com/projects/CodeandCopper1/UMR

FIRMWARE:

The code in the src/ folder can be assembled for the PIC16F1939 device using Microchip's MPASM assembler. Selected firmware images are located in the hex/ folder.
