The ARV6X by Ark Electronics is a tiny flight controller that follows the latest Pixhawk v6 set of standards. The open source device features a high-performance STM32 microcontroller along with triple synced IMUs.

The ARV6X comes in a System-on-Module form-factor and integrates the STM32H753 microcontroller which is a mandatory specification for the Pixhawk 6V standards. For reference, see the table below for other required interfaces defined in DS-010 Pixhawk Autopilot Bus Standard document.

• STM32H743IIK6 — Single Core 32-bit Arm Cortex-M7 (up to 480MHz) w/ double precision FPU; L1 Cache 16 Kb; 2MB Flash; 1MB RAM;

Some of the sensors onboard include a 6-axis MEMS motion tracking device (3-axis gyroscope + 3-axis accelerometer), a 6-axis SmartIndustrial MotionTracking chip (3-axis gyroscope + 3-axis accelerometer) and a 3-axis digital compass. Additionally, there is a 24-bit absolute barometric pressure low-power sensor.
