WS8901D37 is a LoRa wireless digital transmission radio designed and produced by Chengdu Silent Smart Technology Co., Ltd. It has increased power amplifier (PA) and low noise amplifier (LNA) to improve the transmit power and receive sensitivity, and at the same time, the communication distance will be far more than the 30dBm low-power radios, and supports industrial-grade RS485 communication interface. 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 environments.

WS8901D37 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.
