miniMACRO5

QMK-powered macropad based on Arduino Pro Micro. Supports a mix of up to 5 rotary encoders or mechanical switches with optional RGB underglow.

Bill of materials (BOM)

Required components

1. Arduino Pro Micro with headers - available from SparkFun, eBay, Amazon, etc.
2. Rotary encoders - Bourns PEC12R and PEC11R, Alps, and the cheap Chinese versions have been tested. Any quadrature encocder that fits should work. Supports switch encoders.
3. Cherry MX-style switches
4. Keycaps for your chosen switches
5. Case (3d printable STL in /hardware)
6. 4x 4mm M2 mounting screws
7. Electrical insulation tape (if you do not have any, at this low voltage and current, regular clear tape will suffice)

Optional components

1. Reset switch
2. ICSP headers (only required to flash the Arduino if the Caterina bootloader is not present)
3. WS2812 LED strip (for RGB underglow)
