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. | | | | | | | | | | | | | | ADC | Vbat sensor | 0\~30V | 1K:20K divider builtin | BATT\_VOLT\_PIN BATT\_VOLT\_MULT | 14 21.0 | | Current sensor | 0\~3.3V | onboard current sense | BATT\_CURR\_PIN BATT\_AMP\_PERVLT | 15 40 | | | | | | | | | | I2C | I2C1 | 5V tolerant I/O | Compass | COMPASS\_AUTODEC | 1 | | onboard Baro SPL06-001 | Address | 0x76 | | | | | Digital Airspeed I2C MS4525 DLVR-L10D | ARSPD\_BUS ARSPD\_TYPE ARSPD\_TYPE | 1 1 9 | | | | | | | | | | | | UART 5V tolerant I/O | USB | USB | | console | SERIAL0 | | TX3 RX3 | USART3 | NO DMA | telem2 | SERIAL2 | | | TX5 RX5 | UART5 | NO DMA | **GPS1 \*\*\*** | SERIAL3 | | | TX4 RX4 | UART4 | NO DMA | **GPS2 \*\*\*** | SERIAL4 | | | TX2 RX2 SBUS | USART2 | with DMA | RC input/Receiver | SERIAL6 | | | RX2 | IBUS/DSM/PPM | BRD\_ALT\_CONFIG 0 Default | | | | | Sbus pad | SBUS | | | | | | TX2 & RX2 | CRSF | BRD\_ALT\_CONFIG 1 SERIAL6\_PROTOCOL 23 | SERIAL6\_OPTIONS 0 | | | | TX2 | uninverted FPort (hacked) | SERIAL6\_OPTIONS 4 | | | | | TX2 | SRXL2 | SERIAL6\_OPTIONS 4 | | | | * \*\*\* If connecting just one GPS to UART4(TX4/RX4), pls set SERIAL3\_PROTOCOL = -1 or non “5”. otherwise ArduPilot will stop searching for GPS during bootup if not found on the first port(SERIAL3/UART5) configured for GPS protocol. **SD card logging** * set LOG\_BACKEND\_TYPE = 1 (File) **Frsky Smartport Telemetry** * non-inverted (hacked) S.Port signal * any spare Uart\_TX * SERIALx\_BAUD 57 * SERIALx\_OPTIONS 7 * SERIALx\_PROTOCOL 4 or 10(for yaapu) **Relay(PINIO)** * PINIO1, Vbat output ON/OFF, ON by default * PINIO2, PIO2 pad output Low/High Level, Low Level by default ## GPIOs * PA4 PINIO1 OUTPUT GPIO(81) LOW * PB5 PINIO2 OUTPUT GPIO(82) LOW ## RCx\_OPTION: RC input option * 28 Relay1 On/Off * 34 Relay2 On/Off e.g. * RELAY1\_FUNCTION 1 * RELAY1\_PIN 81 * RC7\_OPTION 28 //Use CH7 of Transmitter to control Vbat output ON/OFF * RELAY2\_FUNCTION 1 * RELAY\_PIN2 82 //PIO2 pad * RC8\_OPTION 34 //Use CH8 of Transmitter to control PIO2 Low/High Level The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200. Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen. If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.
