FSC-BW2232 Wi-Fi 4 & Bluetooth 5.2 Module with SDIO/UART/PCM Interfaces


The Feasycom FSC-BW2232 is a small size and low profile of Wi-Fi + BT combo module with LGA module. Its board size is 17 × 17 mm. It can be easily manufactured on SMT process and highly suitable for tablet PC, mobile device and consumer products. It provides SDIO 2.0 interface for Wi-Fi to connect with host processor and high speed UART interface for Bluetooth 5.2. It also has a PCM interface for audio data transmission with direct link to external audio codec via Bluetooth controller. The Wi-Fi throughput up to 150 Mbps in theory by using 802.11n technology. FSC-BW2232 can be customized with different configurations, such as antenna and PIN. The optional models include FSC-BW2232, FSC-BW2232C, FSC-BW2232E, FSC-BW2232EA, FSC-BW2232EB, and FSC-BW2232EC.
