[IC] : AX5043 [Frequency] : 433MHz [Power] : 17dBm [Distance] : 2

0km [Interface] : UART E31-T50S2 is a wireless transceiver module based on AX5043 from AXSEM(can be t ransmitter and receiver)

The module uses FEC (forward error correction) algorithm,which greatly improve the anti-interference ability
