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

Attach an SWD probe

Use the USB supply from the required step. Configure the probe for a powered 3.3 V target. Connect the probe’s reference input to the board logic rail, then wire SWDIO, SWCLK and ground.

Bench checks

  • Check pin 1 orientation and verify each connection with the cable unplugged.
  • Select the exact MCU and use a low SWD clock for the first connection.
