Product Descriptions

E22-900M33S is based on the new generation LoRaTM RF chip SX1262 produced by Semtech in the United States. It is independently developed with a maximum power of 2W and is suitable for 868/915MHz surface mount LoRaTM wireless modules. It uses an industrial grade high-precision 32MHz crystal oscillator.

Due to the use of the original imported SX1262 as the module core, a power amplifier (PA) and a low-noise amplifier (LNA) are built in on the original basis, which not only achieves a maximum transmission power of 2W but also further improves the receiving sensitivity. The overall communication stability is significantly improved compared to products without power amplifiers and low-noise amplifiers. Compared with the previous generation LoRaTM transceiver, the anti-interference performance and communication distance have been improved, further widening the gap with products using FSK and GFSK modulation methods. This product can cover a wide applicable frequency range of 850-930MHz and is backward compatible with SX1278 and SX1276.

As this module is a pure RF transceiver module, it requires the use of MCU drivers or specialized SPI debugging tools.
