UBS programmer for direct setting of BlHeli_S and BlHeli_32 ESCs via computer with BlHeli Suite configurator. Common servo connector from the ESC can be pluged into the programmer. Connect the battery to the ESC and plug the programmer into USB port. In BlHeli Suite, select the USB/Com interface and you can set the ESC even without a flight controller. The USB Programmer is thus particularly suitable for pilots of monoplanes and model airplanes.
