Introduction
The E22-400M30S is a 433MHz/470MHz SMD LoRa wireless module based on the SX1268 chip. It integrates a power amplifier and a low-noise amplifier, delivering a maximum transmit power of 1W with enhanced receive sensitivity. Compared to its predecessor, it offers significant improvements in communication stability, anti-interference performance, and communication range. The module features a high-precision 32MHz crystal oscillator, covers an ultra-wide frequency range of 410 to 493MHz, and is backward compatible with SX1278 and SX1276 chips. The module itself is an RF transceiver module only; users must drive it with a microcontroller or a dedicated SPI debugging tool.
