Description

The E22-400M22S is based on the SX1268, a new generation LoRa RF chip manufactured by Semtech USA. It is a very small and self-developed 433MHz, 470MHz SMD LoRa

Because it adopts the original SX1268 as the main core, the anti-jamming performance and communication distance are further improved compared to the previous generation LoRa transceiver. Thanks to the new LoRa modulation technology, the anti-interference performance and communication distance are far superior to the current FSK and GFSK modulation products. This module is mainly intended for smart home, wireless meter reading, scientific and medical research and long-distance wireless communication equipment. RF performance and component selection are in line with industrial grade standards, and these products are already FCC, CE and RoHS certified, so users don't have to worry about performance. Adopted high precision 32MHz industrial crystal, the product can cover 410-493MHz ultra-wide frequency range, and is backward compatible with SX1278 and SX1276.

Since the module is only an RF transceiver module, users need to use the MCU driver or use a dedicated SPI debugging tool.
