RC Input

RC input is configured on the RCIN pin, at one end of the servo rail. This pin supports all unidirectional RC protocols. For bi-directional protocols, such as CRSF/ELRS, UART8 can be set to protocol "23" and the reciever tied to RCIN (shared with UART8 RX) and UART8 TX. In this case, the RC_PROTOCOLS parameter should be set to the expected protocol type to avoid accidental erroneous detection by the RCIN path.

PWM Output

The VUAV-V7pro supports up to 14 PWM outputs,support all PWM protocols. Outputs 1-12 support DShot. Outputs 1-8 support bi-directional Dshot. All 14 PWM outputs have GND on the top row, 5V on the middle row and signal on the bottom row.

The 14 PWM outputs are in 4 groups:

• PWM 1, 2, 3 and 4 in group1
• PWM 5, 6, 7 and 8 in group2
• PWM 9, 10, 11 and 12 in group3
• PWM 13, 14 in group4

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

GPIOs

All 14 PWM channels can be used for GPIO functions (relays, buttons, RPM etc). The pin numbers for these PWM channels in ArduPilot are shown below:

PWM Channels	Pin	PWM Channels	Pin
PWM1	50	PWM8	57
PWM2	51	PWM9	58
PWM3	52	PWM10	59
PWM4	53	PWM11	60
PWM5	54	PWM12	61
PWM6	55	PWM13	62
PWM7	56	PWM14	63

Analog inputs

The VUAV-V7pro flight controller has 5 Analog inputs

• ADC Pin2-> Battery Current
• ADC Pin16 -> Battery Voltage
• ADC Pin19 -> ADC 3V3 Sense
• ADC Pin3 -> ADC 6V6 Sense
• ADC Pin9 -> RSSI voltage monitoring

Battery Monitor Configuration

The board has voltage and current inputs sensor on the POWER1 ADC and POWER2 CAN connector.

The correct battery setting parameters are:

Enable Battery1 monitor:

• BATT_MONITOR 4
• BATT_VOLT_PIN 16
• BATT_CUR_PIN 2
• BATT_VOLT_MULT 15.7 (may need adjustment if supplied monitor is not used)
• BATT_AMP_PERVLT 60.61 (may need adjustment if supplied monitor is not used)

Enable Battery2 monitor (if used):

• BATT2_MONITOR 8

Loading Firmware

The VUAV-V7pro flight controller comes pre-installed with an ArduPilot compatible bootloader, allowing the loading of *.apj firmware files with any ArduPilot compatible ground station.
