WS8901B30 is a LoRa wireless digital transmission radio designed and produced by Chengdu Silent Smart Technology Co., Ltd; internal increase PA, LNA, improve the transmit power and receive sensitivity at the same time, the communication distance will be far beyond the 22dBm low-power radios, support for industrial-grade RS485 communication interface with anti-reverse protection, over-wire protection, lightning protection, antenna surge protection and other protective measures to enhance the radio's complex environmental adaptation. It supports industrial grade RS485 communication interface, and has various protection measures such as anti-reverse protection, over-connection protection, lightning protection, antenna surge protection, etc., which enhances the radio's adaptability to complex environments.

WS8901B30 works in the voltage range of 8V~28V, and can be configured through the AT command on its related parameters, 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.
