LLCC68 433MHz Lora FSK Wireless FR SPI Module E220-400M33S 33dbm Long Distance 16km PA+LNA Industrial Grade High Speed

E220-400M33S is based on LoRa TM RF chip LLCC68.

The E220-400M33S is a self-developed 2W max power LoRa TM wireless module based on LoRa TM RF chip LLCC68, which is suitable for 433/470MHz SMD LoRa TM wireless module, and uses an industrial-grade high-precision 32MHz crystal. Due to the original imported LLCC68 as the core of the module, built-in power amplifier (PA) and low noise amplifier (LNA) on the basis of the original, so that the maximum transmit power of 2W at the same time, the reception sensitivity has also been further improved, the overall stability of communication compared with the product without power amplifier and LNA greatly improved.

The overall communication stability is significantly improved over products without power amplifiers and low-noise amplifiers. Compared with the previous generation of LoRaTM transceivers, the anti-jamming performance and communication distance have been improved, further widening the gap with FSK and GFSK modulation products. The product can cover an ultra-wide frequency range of 410~493MHz.

Since this module is a pure hardware RF transceiver module, it needs to be driven by MCU or use special SPI debugging tool.
