[Introduction]:E62-433T20S is a full-duplex wireless data transmission module with "point-to-point" transmission and UART interface. It has transparent transmission mode, operates in the 425~450.5MHz frequency band (default 433 MHz), has a transmission power of 100mW, full-duplex, TTL level output, is compatible with 3.3V and 5V IO port voltages, uses a serial port for data transmission and reception, and lowers the threshold for wireless applications. The module has a frequency hopping spread spectrum function (FHSS). During the data transmission process, the module will automatically synchronize the frequency hopping algorithm in up to 52 frequency points (users can customize the frequency modulation number and sequence), which greatly improves the module's anti-interference ability. The 433M frequency hopping technology is in a leading position in the industry.
