UART Mapping

The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the receive pin for UARTn. The Tn pin is the transmit pin for UARTn.

Name Pin Function
SERIAL0 OTG1 USB
SERIAL1 TX6/RX6 UART1 (Telem1)
SERIAL2 TX3/RX3 UART2 (Telem2 buadrate 921600)
SERIAL3 TX1/RX1 UART3 (GNSS)
SERIAL4 TX4/RX4 UART4 (Reserve for GNSS2)
SERIAL5 TX2/RX2 UART5 (Debug)

RC Input

RC input is configured on the RCIN pin by PA15 TIM2_CH1 TIM2 , at one end of the servo rail, marked RC in the above diagram. This pin supports PPM and S.Bus. protocols.

OSD Support

QioTek AdpetF407 supports OSD using OSD_TYPE 1 (MAX7456 driver).

PWM Output

The QioTek AdpetF407 AIO supports up to 12 PWM outputs. All 14 PWM outputs have GND on the top row, 5V on the middle row and signal on the bottom row.

The 12 PWM outputs are in 3 groups:

PWM 1 and 4 in group1 PWM 4 and 8 in group2 PWM 9 and 12 in group3

Channels within the same group need to use the same output rate. If any channel in a group uses DShot or then all channels in the group need to use DShot.

CAN Port

The CAN port is disabled by default. Enable the CAN port setting the parameters CAN_P1_Driver to 1 (DroneCAN protocol).

Battery Monitoring

The board has two dedicated power monitor ports on 6 pin connectors. The correct battery setting parameters are dependent on the type of power brick which is connected.

The correct battery setting parameters are:

BATT_VOLT_PIN 2 BATT_CURR_PIN 3 BATT_VOLT_MULT 20.000 BATT_AMP_PERVLT 60.000 BATT2_VOLT_PIN 14 BATT2_CURR_PIN 15 BATT2_VOLT_MULT 20.000 BATT2_AMP_PERVLT 60.000

In addition, the builtin voltage divider circuit can be used by Solder pad to switching to share the battery voltage monitoring by power2 support to 6S.

If you want to use the built-in voltage monitor on power 1, you can manually invert the BATT_ VOLT_ PIN to 14, BATT_ CURR_ PIN to 15, BATT2_ VOLT_ PIN to 2, BATT2_ CURR_ PIN to 3.

Built-in BEC The built-in BEC 5V output has a starting voltage of 2S, and 9V/12V has a starting voltage of 3S/4S respectively.

Compass

The QioTek AdpetF407 has a builtin QMC5883 compass. Due to potential interference the board is usually used with an external I2C compass as part of a GPS/Compass combination.

Loading Firmware

Initial firmware load can be done with DFU by plugging in USB with the bootloader button pressed. Then you should load the "with_bl.hex" firmware, using your favourite DFU loading tool.

The AdeptF407 auto pilot pre-installed with an ArduPilot compatible bootloader. Updates should be done with the *.apj firmware files.
