Baite · This map follows the BTE14-07A PCB. The numbered silkscreen follows the Maple Mini convention. Identify the fitted MCU before selecting the memory layout.

Power the board from USB

Required

Use a single USB cable to power the board through its native connector. Leave external power headers disconnected. Check the 3.3 V rail before attaching the debug probe.

Bench checks

  • Identify the USB power input and ground in the board schematic.
  • Measure roughly 3.3 V between the board logic rail and ground. Check for a short or wrong connector if the rail is low.

Connection scenarios

Connect a 3.3 V UART console

Use an external 3.3 V logic-level adapter and keep the board on USB power. Cross transmit and receive, share ground and match the serial framing.

Bench checks

  • Leave the adapter’s supply output disconnected.
  • Enable USART1 on PA9/PA10 and verify that the host receives a known test string.
