Product Descriptions

E32-400M33S is a self-developed 410~493MHz surface mount LoRaTM wireless module based on SX1278, with a maximum transmission power of 2W.

Due to the use of the original imported SX1278 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 1W but also further improves the receiving sensitivity. The overall communication stability is significantly improved compared to products without power amplifiers and low-noise amplifiers. Due to its advanced LoRaTM modulation technology, its anti-interference performance and communication distance far exceed those of current FSK and GFSK modulation methods. This module is mainly designed for smart homes, wireless meter reading, scientific research and healthcare, as well as long-distance wireless communication devices.

Due to RF performance and component selection following industrial grade standards. As this module is a pure RF transceiver module, it requires the use of MCU drivers or specialized SPI debugging tools.
