The BL Heli USB Programmer can be used to program a BLHeli-32 (and a BLHeli-S we think) ESC using a PC. This device replaces the Arduno Nano usually used. Works with all Dualsky Summit 30, 60 and Lite ESCs except for the Light 100A ESC.
You will need a suitable USB serial driver. Download the BLHeli-32 Suite from Github. More info here.
