DESCRIPTION OF USE
Our company has developed a wireless remote control micro LED control board. It adopts European brand radio frequency wireless data transmission and receiving chip, which has high receiving sensitivity and strong anti-interference ability. It can realize wireless signal input to data output without any additional circuit; learning type single-chip microcomputer decoding, can learn multiple remote controllers ; The operation is simple and flexible. Use MOS tube switch to achieve high current.
Wireless signal input and data signal output is possible without any external circuit. This product has good selectivity and stray radiation suppression ability, easy to pass CE, FCC international certification; With good local vibration radiation suppression ability, multiple receiving modules can work together (i.e. single sending and multiple receiving) without mutual interference, and using together does not affect the receiving distance. Users only need to add a simple data decoding circuit, it can easily achieve the development of wireless products.
Car remote control door switch (RKE);Remote control door opening machine; Wireless security alarm; Wireless doorbell; Wireless controller; Wireless data transmission;
Please short-circuit the mode switching pad with a wire iron to obtain the switching of the working mode. Pairing method:
1. After short-circuiting the learning contact for 3 seconds, the indicator light will automatically go out to enter the learning state, and release the learning contact.
2. Press any key on the remote control, the indicator light flashes 4 times quickly, indicating successful learning.
Keep shorting the learning contacts, and the indicator light turns from off to steady on to indicate that all is cleared.
