EBYTE E220-400M22S

The E220-400M22S is a compact module developed based on the LLCC68 RF chip. The module employs LoRa modulation technology, offering superior anti-interference performance and communication range compared to FSK and GFSK modulation products. It supports a wide frequency range of 410~493MHz and is primarily designed for smart home, wireless meter reading, scientific research, medical, and long-range wireless communication applications. As a pure RF transceiver module, it requires an MCU or a dedicated SPI debugging tool for operation.
