From the project
Electronics board for Wanos
Structured notes and read-only KiCad projects for legacy WISC hardware. Current WanOS runs on WISC in the field — mainly the 2.5.3 I/O carrier plus the 2.6.4 HDMI board on the Pi that drives LCD screens.
Read-only rule: Do not edit KiCad sources here — see .cursor/rules/wisc-boards-readonly.mdc. New design work lives in projects/wanos-board/ (wanos-pcb-v1).
