Firmware:
PWM Frequency: 48KHz
ESC Protocol: PWM / DShot300 / DShot600 (support BDShot)
Continuous Current: 45A × 4
Voltage Support: 2-6S (5.6V - 27V)
Ardupilot:
SERIAL0 → USB
SERIAL1 → UART1 (MAVLink2, DMA-enabled)
SERIAL2 → UART2 (DisplayPort, DMA-enabled)
SERIAL3 → UART3 (GPS, DMA-enabled)
SERIAL4 → UART4 (MAVLink2, DMA-enabled)
SERIAL5 → UART5 (DMA-enabled)
SERIAL6 → UART6 (RCIN, DMA-enabled)
SERIAL8 → UART8 (DMA-enabled)
PX4:
ttyACM0 → USB
ttyS0 → TELEM1 → UART1
ttyS1 → GPS2 → UART2
ttyS2 → GPS1 → UART3
ttyS3 → TELEM2 → UART4
ttyS4 → TELEM3 → UART5
ttyS5 → RC → UART6
ttyS7 → TELEM4/SERIAL4 → UART8
The default RC input is configured on UART6. The SBUS pin is inverted and connected to RX6. Non-SBUS, single-wire serial inputs can be tied directly to RX6 if the SBUS pin is left unconnected. RC can also be used on UART2, UART4, or UART8 by setting SERIALn_PROTOCOL=23 and changing SERIAL6_PROTOCOL to a different value.
Supports OSD using OSD_TYPE 5 (MSP_DISPLAYPORT).
SH1.0-6P connector supports DJI Air Unit / HD VTX connection (DisplayPort protocol). Pin 1 supplies 12V — ensure compatibility before connecting devices that require 5V.
Supports up to 9 PWM outputs.
Channels 1–8 support DShot and bi-directional DShot (BDShot)
Note: PX4 & INAV currently do not support BDShot
Output Groups:
Group 1: PWM 1, 2, 3, 4
Group 2: PWM 5, 6
Group 3: PWM 7, 8, 11 (Note: PWM11 is LED. If used for serial LED, PWM7 and PWM8 must also be used for LEDs)
No built-in compass. External compass can be connected via I2C on SDA/SCL.
