E42-400M20S Wireless module small size low power consumption 433/470MHz RF transceiver remote control module HW3000
[Introduction]：E42-400M20S is an SPI hardware module designed based on the original HW3000 RF chip of Shanghai Neusoft Carrier Microelectronics. It is half-duplex, integrates transceiver and receiver, transparent transmission mode, patch type, operating frequency band is 428~522MHz, and transmit power is 100mW. Suitable for a variety of environments, with high receiving sensitivity, strong anti-interference, and supports the development of low power consumption.
