5.4 Receiver accessories

5.4.1 DuPont Cables

：

One 7pin 20cm

；

two 3pin 20cm. (color may be different for different batch.)

5.4.2 DC-DC module (BEC/UBEC), Input: DC 18-75V Output: DC 5V, 1200ma. It can convert main battery

voltage to 5V output for receiver. If your ESC doesn’t have built-in 5V power supply, you will need
this module for receiver (this module needs to be purchased separately).
