The properties of the receiver and the transmitter to be used are as follows.
UTR-C12U UHF FSK transceiver module, Basic Standards of Short Distance Access Radio Devices Regulation on the Principles of Installation and Use (TGM-STK-001) 433-434MHz. Designed to cover the ISM band related part. UTR-C12U is designed for PCB assembly. An antenna can be connected using a simple cable.
It seems like the UTR-C12U uses UART to communicate with CPU/PSoC. Can you kindly attach the english version of the datasheet, so we can confirm.
