Anyone who uses ESCs that need programming or throttle range calibration on their multicopters, knows what a pain it can be, especially when all your ESCs are soldered to your power board, and all the ESC are beeping while you try to program each one separately! Not any more!

Simply connect the male to male servo lead (provided) to the throttle output on your Rx and plug up to 4 ESCs into this little board at the same time. Now you can program and calibrate all your ESC simultaneously in just a few seconds!
