WS8901B37 is a LoRa wireless digital transmission radio designed and produced by Chengdu Silent Smart Technology Co., Ltd.; internal increase in power amplifier (PA), low noise amplifier (LNA), to improve the transmit power and receive sensitivity at the same time, the communication distance will be far more than the 30dBm low power radio, support industrial-grade RS485 communication interface, with anti-reverse connection protection, over-connection protection, It supports industrial-grade RS485 communication interface, and has various protection measures such as anti-reverse connection protection, over-connection protection, lightning protection, antenna surge protection, etc., which enhances the radio's adaptability to complex environment.

WS8901B37 works in the voltage range of 9V~36V, and can be configured through the AT command, which is convenient for customers to use in different application scenarios; LoRa direct-sequence spread spectrum technology, due to its centralized power density, will bring a longer distance while improving the anti-jamming ability.
