4-Channel Switching Value RF Receiving Module with Local Control 

DL-RX06C-KO4 is a RF receiver module that supports function keys, small size, high sensitivity, super-heterodyne ISM band with decoding (learning code). Adopt high cost-effective wireless data receiving chip and low power consumption single chip, have higher receiving sensitivity, and support 3V-5.5V wide voltage power supply, built-in image suppression of RF chip, good anti-interference performance. The module sets the logic state through the 0R resistance of the 14th PIN of the MCU to achieve the output mode required by the customer application, and independently leads out the LED code-code status indication and KEY-Study to learn the code-code button two ports. The customer can switch the code button SW and the code instruction The light LED is led to the circuit board or casing of the product, which is convenient for the user to operate the code.

The pins of this DL-RX06C-KO4 wireless module adopt 2.0mm pitch, which reduces the size of the module. The double-sided in-line pad T-type board design. The product application bottom plate adopts slotted in-line method, insert the module directly on the circuit board and use wave soldering , Eliminate the soldering of the black pin header and reduce the module height to 10mm. The module is compatible with PT2262 and 1527 encoding. You can also customize and develop the corresponding decoding and receiving module according to different remote control encoding types ODM.
