Product instruction
BL-R8723RD2 is a small size and low profile of WiFi+BT combo module with LGA (Land-Grid Array)footprint, board size is 12mm*12mm with module height of 1.6mm. It can be easily manufactured on SMT process and highly suitable for tablet PC, ultra book, mobile device and consumer products. It provides GSPI/SDIO interface for WiFi to connect with host processor and high speed UART interface for BT. It also has a PCM interface for audio data transmission with direct link to external audio codec via BT controller. The WiFi throughput can go up to 150Mbps in theory by using 1×1 802.11b/g/g MIMO technology and Bluetooth can support BT2.1+EDR/BT3.0 and BT4.0.
