Pixhawk digital outputs and inputs (Virtual Pins 50-55)¶ The Pixhawk has no dedicated digital output or input pins on its DF13 connectors, but you can assign up to 6 of the “AUX SERVO” connectors to be digital GPIO outputs/inputs.

Pixhawk6X® is the latest update to the successful family of Pixhawk® autopilots made by Holybro, featuring STM32H7 cpus, vibration isolation of IMUs, redundant IMUs, double redundant barometers on separate buses, IMU heating, and integrated Ethernet for high speed connections to companion computers.

Pixhawk can be powered off the servo rail instead of from a power module. This is achieved by connecting a 5V BEC (with or without a servo) to a power (+) pin and a ground (-) pin of the “MAIN OUT” or “AUX OUT” pins.

Pixhawk Wiring Quick Start¶ This article provides high level information about how to power Pixhawk and connect its most important peripherals.

Pixhawk 6C 6C Mini Flight Controller¶ Pixhawk6C is the latest update to the successful family of Pixhawk® autopilots made by Holybro, featuring STM32H7 cpus, vibration isolation of IMUs, redundant IMUs, and IMU heating. It comes in two form factors.

For boards marked “Pixhawk”, Pixhawk1 firmware is usually the best choice. Warning some boards labeled as Pixhawk 2.4.x may have sensor substitutions which may lead to pre-arm checks or no secondary IMU.

Advanced Pixhawk Quadcopter Wiring Chart¶ Jethro Hazelhurst produced this magnificent Pixhawk wiring chart for a Quadcopter for us. (Other autopilots will be wired similarly) (Control Scroll wheel will let you zoom in on the image below!) This chart Illustrates a quadcopter with a variety of options.¶

Pixhawk 5X® is the latest update to the successful family of Pixhawk® autopilots made by Holybro, featuring vibration isolation of IMUs, triple redundant IMUs, double redundant barometers on separate buses, and IMU heating.

Some of the LED patterns have associated sound/tone patterns as listed in Sounds (Pixhawk). Boards with 1 or 2 Notify LEDS ¶ These boards have one(LED A) or two(LED A and LED B) leds on the board, normally, but not always, green and blue, respectively.

The board comes pre-installed with an ArduPilot compatible bootloader, allowing the loading of xxxxxx.apj firmware files with any ArduPilot compatible ground station. Firmware for this board can be found here in sub-folders labeled “PH4-mini”.
