The WS8901D30 is a LoRa wireless data transmission radio designed and manufactured by Silent Smart Technology Co., Ltd. Its internal PA and LNA improve transmit power and receive sensitivity, extending its communication range far beyond that of low-power radios up to 22 dBm . 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 WS8901D30 operates within an 8V to 28V voltage range and is configurable via AT commands, facilitating user adaptation to diverse application scenarios. LoRa's direct-sequence spread spectrum technology, with its concentrated power density, offers greater range and improved anti-interference capabilities. The WS8901D30 radio also includes a serial port and SWD download interface, allowing for custom development (we can also customize standard LoRaWan and Alibaba LinkWan nodes).
