Baite Maple Mini connection guide
Baite Maple Mini Baite BTE14-07A wiring guide with power, signal assignments, and bench checks.
Baite BTE14-07A
45 contacts Current packagePower the board from USB
RequiredUse 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.
- USB power input
- USB host VBUS
- VCC (H3-1)
- USB return
- USB host ground
- GND (H3-5)
- Board logic rail
- Vcc (H1-1)
- 3.3 V measurement point
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.
- Target reference
- Vcc (H1-1)
- Probe VTref input
- Ground
- GND (H1-2)
- Probe ground
- SWD data
- 22 (H2-11)
- Probe SWDIO
- SWD clock
- 21 (H2-10)
- Probe SWCLK
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.
