WS8406DHS is a LoRa wireless transceiver SoC module designed and produced by Silent-Smart which supports multiple frequency bands. It has the characteristics of long communication distance, extremely low low-power mode current, supports 433/470 frequency bands, and has a maximum transmission power of 30dBm.

WS8406DHS is the first domestic SoC chip launched by ASR that supports LoRa's LPWAN wireless communication protocol. ASR6601 integrates a general-purpose microcontroller and RF unit on a single chip, including RF transceiver, modem and a 32-bit MCU with a 48 MHz main frequency and Arm Cortex M4 architecture, with a Flash capacity of 128kB and an SRAM capacity of 16kB. It supports LoRaWAN and LinkWAN multiple protocol standards and is suitable for a variety of IoT application scenarios. It is currently the best choice for domestic chips for LPWAN applications.

WS8406DHS is a hardware SoC module and cannot be used independently. Users need to carry out secondary development (our company can customize standard LoRaWan and Ali linkWan nodes).
