@Mouhamed-Ndoye What is the interface to control these propulsion units? Is it standard PWM? VOXL does not have a flight controller integrated, it is only a companion computer. But VOXL 2 and VOXL 2 mini support either PX4 or ArduPilot. They, however, do not have any PWM outputs. You would need to use our VOXL 2 Digital IO expander board (https://www.modalai.com/products/voxl2-io?variant=40610514206771) in addition to the VOXL 2 to get that added capability.
