FSC-BW157 Wi-Fi 6 & Bluetooth 5.0 Module with SDIO and UART Interfaces


The Feasycom FSC-BW157 module adopts a high-performance dual-band Wi-Fi 6 and dual-mode Bluetooth 5.0 single-chip SoC and supports all the indicators of Wi-Fi 6 with the lowest power consumption in the industry. FSC-BW157 integrates Cortex-M4F CPU and the main frequency can reach 480 MHz. With the help of the internal integrated 992KB SRAM, 752KB ROM and up to 128Mbit on-chip SPI flash memory, it provides users with powerful hardware support and can be used for secondary development. FSC-BW157 has a wealth of peripheral interfaces that can be used for control and data transmission through SPI/SDIO/I2C/UART, and can be quickly applied to any microcontroller-based design. FSC-BW157 module supports the standard IEEE 802.11 a/b/g/n/ac/ax protocols and the complete TCP/IP protocol stack. Users can use this module to add networking functions to existing equipment, or build an independent network controller. FSC-BW157 module provides maximum practicability at the lowest cost, providing unlimited possibilities for Wi-Fi function embedding in other systems.
