FSC-BW246 Single-band Wi-Fi 4 Module (2.4GHz, dual-mode Bluetooth 4.2)
FSC-BW246 is an advanced Bluetooth specially designed for automotive applications 4.2 Dual Mode and Wi-Fi 4 Mods. Provides flexible control and data transmission functions through interfaces such as SPI, I²C and UART. The module supports IEEE 802.11b/g/n, TCP/UDP/HTTP/MQTT protocols, and Bluetooth SPP/GATT/HID profiles, making it a cost-effective solution for integrating Wi-Fi and Bluetooth into various systems. In addition, with Feitong firmware, the Bluetooth function can be easily accessed through UART AT commands.
