Product Descriptions

E220-400M33S is independently developed based on the new generation LoRaTM RF chip LLCC68 produced by Semtech, with a maximum power of 2W and suitable for 433/470MHz surface mount LoRaTM wireless modules. It uses an industrial grade high-precision 32MHz crystal oscillator.

Due to the use of imported LLCC68 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 frequency range of 410~493MHz.

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