E22-900M33S is independently developed based on the new generation LoRa radio frequency chip SX1262 produced by Semtech in the United States. It has a maximum power of 2W and is suitable for 868/915MHz patch-type LoRa wireless modules. It uses an industrial-grade high-precision 32MHz crystal oscillator. Compared with the previous generation LoRa transceiver, the anti-interference performance and communication distance have been improved, further widening the gap with products with FSK and GFSK modulation methods. This product can cover an ultra-wide applicable frequency range of 850 to 930MHz and is backward compatible with SX1278 and SX1276. Since this module is a pure radio frequency transceiver module, it needs to use an MCU driver or a dedicated SPI debugging tool.
