433MHz RF Receiver Module with Switch Control and Learning Code Function

DL-RX06C is a compact size super heterodyne wireless receiving module with decoding (learning code) function, it is very low power consumption, but high sensitivity. It uses a cost-effective wireless receiving chip and a low power consumption MCU. Its performance indicators and functions are similar to another RF receiving module DL-RX809L, but N3 pair of code keys are added, as well as another N4 pair of ports (for LEDs indicate), so you can lead code keys and relative LEDs to your own product (on the circuit board or housing) for your convenience. 

DL-RX06C pins are changed into 2.0 spacing, which reduces the size of the module. With double-sided direct insert pads, you can make slot pads on your own circuit board, insert the module directly on the circuit board and use wave soldering. The module height will be only 10cm after welding. 

DL-RX06C is compatible with PT2262 and 1527 encoding, which has a lock and non-lock selection port, four-channels switching value output, decodes high level output, you can directly replace the original decoding chip scheme to reduce product cost and reduce product volume. At the same time, the module has a low power mode selection port, and receives the lowest average power consumption of 80 microamps. You can use 3-5V power supply.
