I updated the project specification to reflect the new blind-control remote/receiver system: two PCBs, ESP-NOW wireless, Li-ion battery support, USB-C charging, 5 V boost rails, and receiver-side motor control.
I also captured the key power-risk assumption: the receiver boost/battery path is provisionally sized around a 5 V motor up to ~2 A peak, which could require nearly 4 A from the Li-ion cell at low battery voltage. The actual motor stall current is the main missing requirement before final component selection.
Remaining work:
- Select charger, boost converter, ESP32 module, motor driver, connectors, and support passives.
- Consult datasheets for every IC.
- Add and wire the full schematic for both boards.
- Run design review/ERC and fix violations.
- After schematic is clean, proceed to layout only with confirmation.
