E62-433T20S Wireless Module, 433MHz, 20dBm, Up to 1km Range, Full-Duplex UART, 125°C Operating Temp

The E62-433T20S is a compact, full-duplex wireless UART data transmission module designed for transparent point-to-point communication. Operating in the 425–450.5 MHz frequency band (default: 433 MHz), it supports TTL-level UART interfaces compatible with 3.3V and 5V I/O systems.

With built-in frequency hopping spread spectrum (FHSS) technology, the module automatically hops across up to 52 frequency points during data transmission, significantly enhancing noise immunity and communication stability. This makes the E62-433T20S a robust and easy-to-integrate solution for long-range, interference-resistant wireless serial communication.
