# Accton Godwit G-A1
|
||||
|
||||
:::warning
|
||||
PX4 does not manufacture this (or any) autopilot.
|
||||
Contact the [manufacturer](https://cubepilot.org/#/home) for hardware support or compliance issues.
|
||||
:::
|
||||
|
||||
The G-A1 is a state-of-the-art flight controller developed derived from the [Pixhawk Autopilot v6X Standard](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-012%20Pixhawk%20Autopilot%20v6X%20Standard.pdf).
|
||||
|
||||
It includes an STM32H753 double-precision floating-point FMU processor and an STM32F103 IO coprocessor, multiple IMUs with 6-axis inertial sensors, two pressure/temperature sensors, and a geomagnetic sensor.
|
||||
It also has independent buses and power supplies, and is designed for safety and rich expansion capabilities.
|
||||
|
||||
With an integrated 10/100M Ethernet Physical Layer (PHY), the G-A1 can also communicate with a mission computer (airborne computer), high-end surveying and mapping cameras, and other UxV-mounted equipment for high-speed communications, meeting the needs of advanced UxV systems.

## Wiring Diagram
|
||||
|
||||
|
||||
|
||||
## PWM Output
|
||||
|
||||
PWM M1-M8 (IO Main PWM), A1-A8(FMU PWM).
|
||||
All these 16 support normal PWM output formats.
|
||||
FMU PWM A1-A6 can support DShot and B-Directional DShot.
|
||||
A1-A8(FMU PWM) are grouped as:
|
||||
|
||||
- Group 1: A1, A2, A3, A4
|
||||
- Group 2: A5, A6
|
||||
- Group 3: A7, A8
|
||||
|
||||
The motor and servo system should be connected to these ports according to the order outlined in the fuselage reference for your carrier.
|
||||
|
||||
|
||||
|
||||
## RC Input
|
||||
|
||||
For DSM/SBUS receivers, connect them to the DSM/SBUS interface which provides dedicated 3.3V and 5V power pins respectively, and check above "Pinout" for detailed pin definition.
|
||||
PPM receivers should be connected to the PPM interface. And other RC systems can be connected via other spare telemetry ports.
|
||||
|
||||
|
||||
|
||||
## GPS/Compass
|
||||
|
||||
The Godwit G-A1 has a built-in compass
|
||||
Due to potential interference, the autopilot is usually used with an external I2C compass as part of a GPS/Compass combination.
|
||||
|
||||
|
||||
|
||||
## Power Connection and Battery Monitor
|
||||
|
||||
This universal controller features a CAN PMU module that supports 3 to 14s lithium batteries.
|
||||
To ensure proper connection, attach the module's 6-pin connector to the flight control Power C1 and/or Power C2 interface.
|
||||
|
||||
This universal controller does not provide power to the servos.
|
||||
To power them, an external BEC must be connected to the positive and negative terminals of any A1–A8 or M1–M8 port.
|
||||
|
||||
|
||||
|
||||
## SD Card
|
||||
|
||||
The SD card is NOT included in the package, you need to prepare the SD card and insert it into the slot.
|
||||
|
||||
|
||||
|
||||
## Firmware
|
||||
|
||||
The autopilot is compatible with PX4 firmware. And G-A1 can be detected by QGroundControl automatically. Users can also build it with target "accton-godwit_ga1"
|
||||
|
||||
To [build PX4](../dev_setup/building_px4.md) for this target, open up the terminal and enter:
|
||||
|
||||
```sh
|
||||
make accton-godwit_ga1
|
||||
```
