zmk config repo for the micropad, a seeed studio xiao BLE based macro pad with encoder support.

BOM

Part Name	Number required
Pololu SPDT slide switch (or an equivalent; they're all the same)	1x
Seeed Studio Xiao BLE (nRF52840; don't buy the sense variant - it's costlier and useless for this build.)	1x
A 300mAh battery (it should be okay even if the dimensions don't match too closely.)	1x
Choc Sunset low profile switches + choc compatible keycaps (I got mine at lowprokb.ca)	6x
Alps EC11 compatible encoder (I used a KY-040)	1x
20mm long, 2mm diameter standoffs	4x
M2x0.4 screws (with your choice of head)	8x
Rubber feet	4x
