Tasks
Hardware version
MDD400 v3.0 — ESP32-P4 / MIPI-DSI / LVGL platform re-base, at schematic-capture stage.
V3.0 status
The V3.0 schematic is being captured in KiCad Eeschema. This page tracks the capture and downstream tasks; it will be populated from the working runsheet as sheets are drawn.
The V2.9 → V3.0 next-version backlog carried on the V2.9 Tasks page seeds this work.
