The WS8401FLS is developed based on the ASR6601, the first domestically produced SoC chip from ASR Corporation that supports the LoRa LPWAN wireless communication protocol. It supports the 868/915 MHz frequency bands with a maximum transmit power of 22 dBm.

The ASR6601 integrates a general-purpose microcontroller and a radio frequency unit on a single chip, including an RF transceiver, modem, and a 32-bit MCU with an Arm Cortex M4 architecture running at 48 MHz. It features 128 kB of Flash memory and 16 kB of SRAM, boasting a compact size and ultra-low power consumption. The chip supports an air speed of up to 62.5 Kbps under LoRa modulation and up to 300 Kbps under (G)FSK modulation. It is compatible with multiple protocol standards such as LoRaWAN and LinkWAN, making it suitable for a variety of Internet of Things (IoT) application scenarios. Currently, it stands as the optimal choice for domestic chips in LPWAN applications.

The WS8401FLS is a pure hardware SoC module and cannot be used independently; users are required to perform secondary development. (Our company supports customization of standard LoRaWAN and Ali LinkWAN nodes).
