1. General Description
BL-M8821CS1 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 2.35mm. It can beeasily 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 data rate can go up to 433.3Mbps in theory by using 1stream
802.11a/b/g/n/ac MIMO technology and Bluetooth can support BT2.1+EDR/BT3.0 and BT4.2.
2. The range of applying
MID, networking camera, STB GPS, E-book, Hard disk player, Network Radios, PSP, etc, the device
which need be supported by wireless networking.
