The Holybro PWM Extension Board (PWM EXT Board) is a vital utility breakout board designed to simplify hardware cabling and expand servo/motor connectivity for advanced drone architectures. Specifically engineered to interface with modern compact autopilot systems—including the Pixhawk 4, Pixhawk 6C, Pixhawk Mini Baseboard, and Pixhawk Jetson Baseboard—this breakout module cleanly adapts high-density multi-pin outputs into standard, accessible layouts. It functions seamlessly with both MAIN (I/O) and AUX (FMU) PWM output buses, providing sUAS builders with maximum architectural flexibility when connecting multiple electronic speed controllers (ESCs), steering servos, camera gimbals, or payload drop mechanisms.
Weighing a mere 10 grams, this ultra-lightweight board ensures zero noticeable payload penalty on tight mini-quad or fixed-wing layouts. It isolates signal channels while providing clean grounding paths and direct power distribution to peripheral actuators. By utilizing this board, professional builders eliminate the need for intricate custom wire splicing, mitigating the risk of signal interference, tracking errors, or loose crimp connections on complex enterprise robotic platforms.
