Consumer electronics device. One side has a ESP32-S3 module, a 40 pin ribbon cable female slot, a MICROSD card reader, a 2 pin JST female connector, and then a big empty space on the board for a battery to be glued onto. On the other side there should be a 5x5 button matrix that dosnt have physical like pushy tactile buttons but instead the kind you get one of those silicon pads for

No design changes were made because Agent features are currently unavailable due to insufficient ACUs.
Captured requirements:
  • ESP32-S3 module
  • 40-pin female FFC/FPC ribbon connector
  • microSD socket
  • 2-pin female JST battery connector
  • Large battery mounting area
  • Opposite side: 5×5 PCB contact matrix for a conductive silicone-rubber keypad
Remaining work includes defining dimensions and interfaces, selecting parts, designing the keypad scanning circuit and contacts, creating the schematic, then placing and routing the PCB. Additional ACUs are required to continue execution.
