The WS8901B30 is a LoRa wireless data transmission radio designed and produced by Silent Smart Technology Co., Ltd.It integrates an internal PA and LNA to enhance transmit power and receive sensitivity, significantly extending communication range compared to standard low-power 22dBm radios. It supports an industrial-grade RS485 communication interface and features multiple protections, including reverse polarity protection, over-polarity protection, lightning strike protection, and antenna surge protection, enhancing its adaptability to complex environments.

The WS8901B30 operates within an 8V to 28V voltage range and is configurable via AT commands, facilitating its use in diverse application scenarios. LoRa's direct-sequence spread spectrum technology, with its concentrated power density, offers greater range and improved anti-interference capabilities. The WS8901B30 radio includes a serial port and SWD download interface, allowing for user-friendly development (we can customize standard LoRaWan and Alibaba LinkWan nodes).
