27MHZ 2CH Transmitter + Receiver board + Antenna Wireless Circuit Remote Control Module for DIY Toy Car

Signal frequency: 27 Hz

Supply voltage: transmission and reception are 3V voltage, with 2 AA battery pack on the 5th can be a (battery box link)

Launch panel: B + connected to the cathode, B-then negative, ANT antenna (the antenna wire contact with the ANT on the reverse of the solder, can be fixed welding, you can also use the screw)

Receiving panel: B + then positive, B-connected negative, L and R, respectively, corresponding to the two poles of the motor, ANT antenna

Dimensions: the size of the launch pad 27mm * 40mm, receiving plate size 25mm * 36mm

Use tips:

(1) multiple sets of the same frequency remote control device at the same time at the same time will interfere with each other; if you want multiple sets of remote control devices work at the same location, you must use different frequency remote control devices, such as 27mhz and 49mhz (other remote control link)

(2) If you want to improve the remote control sensitivity, the capacitor can be welded to the motor
