Description
AX5043 433MHz RF Wireless Transceiver Module High Power 1W UART Serial Port to RF Transceiver Transparent Transmission
Product Description
The wireless transparent transmission module based on the radio frequency chip AX5043 (integrated transceiver) uses narrow-band transmission with 1W transmit power. At the same time, the FEC forward error correction algorithm is used to greatly improve the anti-interference ability; at the same time, it can communicate with other modules of the E31 series.
