## Description

40MHz 4-channel transmitter receiver pair, ideal for DIY remote control projects, allows control of two motors in both directions for forward, reverse and direction. It operates at 3-4.5V on the transmitter and 4.5-6V on the receiver, has a range of up to 10 m, offers simple connections for 130 type motors and includes antennas for stable transmission.
Pair of 40MHz transmitter-receiver frequency, with 4 channels, which allows the control of 2 motors in both directions.
This allows, for example, the creation of a remote control car in which one motor is responsible for forward/backward movement and the second can be used to control the direction.
Careful! This kit uses the frequency of 40MHz. To use several modules at the same time, you will have to use modules with different frequencies. DO NOT use powerful motors! This will burn the receiver!
