4-Channel Switching Value RF Receive Module with Decoding (learning code) Function


DL-RXC6A / RXC6B is a low cost, small size, high sensitivity wireless receive module, with decoding (learning code) function, and super heterodyne ISM band. It adopts cost-effective wireless data receiving chip and low power consumption single chip, built-in image suppression of RF chip, can support 2.8V-5.5V wide voltage power supply, which performs high receiving sensitivity, as well as good anti-interference performance.

This Wireless ASK receiving module can meet your needs (realize the application) by setting the logic state of T1 and T2, and independently leads out three ports as following: LED code-checking status indication, SW learning code- checking button, and VT public valid signal indication. The LED indicator and SW learning code-checking button can be led to the circuit board or casing of the product, which is convenient for the user to operate.

DL-RXC6B leads out the T1 and T2 setting ends of the A version. The module pins adopt a 2.0mm pitch to reduce the size of the module. It also adopts T-type board double-sided in-line pad design. Its bottom plate uses a slotted in-line method, which the module can be inserted directly on the circuit board and then wave soldering. By this way, it can save the soldering of the black pin and reduce the height of the module to 10mm.

DL-RXC6A / DL-RXC6B are compatible with PT2262 and 1527 encoding. The corresponding decoding and receiving module can also be ODM (customized) according to different remote-control encoding types.
