[Introduction]：E32-400M33S is a 410~493MHz SMD LoRaTM wireless module with a maximum transmitting power of 2W, which is independently developed based on the SX1278 produced by Semtech in the United States. As the imported SX1278 is used as the core of the module, a power amplifier (PA) and a low noise amplifier (LNA) are built in on the original basis, so that the maximum transmitting power reaches 1W while the receiving sensitivity is further improved, and the overall communication stability is greatly improved compared with products without power amplifiers and low noise amplifiers. This module is mainly aimed at smart homes, wireless meter reading, scientific research and medical treatment, as well as medium and long-distance wireless communication equipment.
