NxtPX4v2 is an open-source hardware flight controller for PX4 and ArduPilot firmware. It features 20x20mm M3 mounting holes, making it suitable for building smaller drones with advanced stabilization and autonomous flight capabilities. The controller includes an SD card slot for storing logs, missions, or terrain elevation maps. The board is powered by a high-performance STM32H743 processor, dual BMI088 gyros, and an SPL06 barometer. It offers 7 UARTs, as well as I2C and SPI buses for connecting peripherals. There are 8 PWM outputs available for motors, servos, switches, or other accessories. The board is also equipped with a USB-C connector, 5V/2.5A, and 12V/2.5A BECs.
