The WS8901B37 is a LoRa wireless data transmission radio designed and produced by Silent Smart Technology Co., Ltd. Its internal power amplifier ( PA) and low-noise amplifier ( LNA) improve transmit power and receive sensitivity, extending the communication range far beyond that of low-power 30 dBm radios. It supports an industrial-grade RS485 communication interface and features multiple protections, including reverse connection protection, overconnection protection, lightning protection, and antenna surge protection, enhancing its adaptability to complex environments.
The WS8901B37 operates within a 9V to 36V voltage range and can be configured via AT commands, facilitating user adaptation to diverse application scenarios. LoRa's direct-sequence spread spectrum technology, with its concentrated power density, offers longer range and improved anti-interference capabilities. The WS8901B37 radio includes a serial port and SWD download interface, allowing for user development (we can customize standard LoRaWan and Alibaba LinkWan nodes).
