LAYOUT
-
AirS: Analog Airspeed sensor (0~3.3V) no voltage divider built-in
Rssi: Analog RSSI ADC, 0~3.3V -
Tx1/Rx1: UART1_Tx/Rx
-
swd/swc: STM32F405RGT6 debug pin
-
Rx2: UART2-RX for Serial_RX by default
- PPM is not supported by INAV
-
Tx2: UART2-TX
- softserial1_tx is an alternative on Tx2 pad in INAV
-
Sbus: UART2_RX + inverter for SBUS receiver
-

-
Tx5/Rx5: UART5_Tx/Rx
-
DA & CL: I2C_SDA, SCL,
- for compass/digital Airspeed
-
5V: onboard BEC 5V 2A cont.
- 5V is not supplied by USB
-
4V5: 4.4~4.8V, Max.800mA,
- 4V5 is also supplied when connecting via USB.
-
G: Ground
DO NOT connect the ESC BEC output (Red wire in the middle of connector) to Vx pad If Vx rail is powered from bottom PDB.
- TX6/RX6: UART6_Tx/Rx
- TX4/RX4: UART4_Tx/Rx
- Vbat: Battery voltage
- onboard battery voltage sense: BATT_VOLT_PIN 14, BATT_VOLT_MULT 21 INAV scale 2100
- Curr: Current signal (0~3.3V)
- onboard current sense: BATT_CURR_PIN 15, BATT_AMP_PERVLT 66.7 INAV scale 150
- 9V: onboard BEC 5V 2A cont. Max.3A
- 9V will increase to 12V if “12V” jumper on bottom PDB is bridged.
- 5V: onboard BEC 5V 2A cont. Max.3A
- G: Ground
- VTx: Video OUT for Video Transmitter
- C1: Camera-1 video IN (Default)
- C2: Camera-2 video IN
- C1/C2 can be switched via ArduPilot Relay or Modes/USER2 (INAV)
- Two cameras should be set with identical video format, both PAL or both NTSC
- PIO1: Low/High level switchable via INAV Modes/USER1 or ArduPilot Relay
- DFU Button: F405 DFU mode, same function as the button on FC board.
- Connect USB to the PC While holding the boot button in.
- Red LED, USB power indicator

Wiring
ArduPlane fw: MATEKF405-TE
INAV fw: MATEKF405TE_SD
- INAV doesn’t support VTOL, F405-VTOL can be used as a normal fixed-wing flight controller
- DJI FPV OSD can work with any spare UART_TX & RX

Mixing Dshot and normal PWM operation for outputs is restricted into groups,
ie. enabling Dshot for an output in a group requires that ALL outputs in that
group be configured and used as Dshot, rather than PWM outputs.
If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo
supports Max. 50Hz, ESC must run at 50Hz in this group.
