FSC-BW151B Wi-Fi 6 & Bluetooth 5.0 Module with SDIO/UART/PCM Interfaces


The Feasycom FSC-BW151B module adopts a high-performance SoC (an industry's leading dual-band Wi-Fi 6 & Bluetooth 5.0 dual-mode single chip). While supporting all the indicators of Wi-Fi 6, the power consumption is the lowest in the industry. FSC-BW151B integrates Cortex-M4F CPU at the same time, the main frequency can reach 480 MHz. With the help of the internal integrated 992KB SRAM, 752KB ROM and up to 128Mbit on-chip SPl flash memory, it provides users with powerful hardware support and can be used for secondary development. FSC-BW151B 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-BW151B module supports the standard IEEE 802.11 b/g/n/a/ac/ax protocol 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-BW151B module provides maximum practicability at the lowest cost, providing unlimited possibilities for Wi-Fi function embedding in other systems.
