Product Description
[Frequency] : 220.125~236.125MHz
[Power] : 22dBm
[Distance] : 5km
[Interface] : UART
[Introduction] : E22-230T22S is a wireless serial port module (UART) based on RF chip. It has multiple transmission modes, working in the 220.125MHz~236.125MHz, (default 230.125MHz).
This product uses LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage. LoRa direct sequence spread spectrum technology will bring longer communication distance, and has the advantages of concentrated power density and strong anti-interference ability.
The module has a software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability. In the case of sudden interference, it can actively correct the interfered data packets, greatly improving reliability and transmission distance. When without FEC, such packets can only be discarded. The module has data encryption. Data transmitted over the air, with randomness, makes data interception meaningless through strict encryption and decryption algorithms.
This module reserves multiple IO interfaces to provide custom development services.It supports packet length setting and also supports different real-time and data packets.
