Wiring / Connections

  • Motor pads: M1, M2, M3, M4
  • Camera pads: CAM, +5V, GND
  • VTX pads (incl. spare pads shown): VTX, GND (power connection depends on VTX requirement)
  • Receiver pads shown: SBUS; DSM receiver example uses RC / 3.3V / GND; SBUS/IBUS uses RC / VCC / GND; CRSF uses RX / TX / VCC / GND
  • UART pads shown: RX1, TX1; RX2, TX2
  • I2C pads: SCL, SDA
  • Other labeled pads: RSSI, LED, BZ, +5V, VBAT, GND

Note: When using SBUS/IBUS/DSM receiver, enable UART2 as Serial RX in the ports configuration.

ESC Setup Note (1S)

If using a 1S battery and the motor is difficult to start, try increasing the ESC starting power to a value that can start the motor (BLHeli_S / Bluejay settings screen).

At only about 4.4g, it helps keep lightweight builds responsive without giving up integrated ESC capability.

Package contents: Ruibet F4AIO 12A board, XT30 lead, wires, capacitor, damping balls, and connector sockets

Included accessories support a clean install with power lead, capacitor, wiring, connectors, and soft mounting hardware.
