1. Introduction
2.4G 4-channel wireless remote controller and้ ๅฅ remote signal receiver module, using 2.4GHz digital wireless communication technology, strong anti-interference ability, long control distance and no directional limitation;The remote control provides 4 independent control channels to meet various operation requirements such as forward, backward, turning, and function switching. The receiver is responsible for receiving and decoding wireless signals, outputting stable serial communication signals, supporting one-key pairing and power-off memory, automatically entering a safe state when the signal is lost. When used together, they can realize stable and reliable long-distance wireless control for intelligent devices such as tracking cars and robots, with simple wiring and compatibility with various development boards and expansion boards.
