a flight control board or equivalent. For this purpose, several communication bus

interfaces (UART, CAN, PWM channel) are present. A potentiometer and a user

button are available for user application. The daughterboard includes a 5 V battery

eliminator circuit (BEC), and the main board embeds an overcurrent/overvoltage and

thermal protection circuit. The form factor makes it suitable for small and very light

R/C vehicles (FPV race drone) and the motor current capability fits the power

requirement of big vehicles, for instance a prosumer drone.
