PRODUCT DESCRIPTION
SM02BD 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 2mm. 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 1x1 802.11n b/g/n MIMO
technology and Bluetooth can support BT2.1+EDR/BT3.0 and BT4.0.
SM02BD uses Realtek RTL8723BS, a highly integrated WiFi/BT single MODULE based on
advanced COMS process. RTL8723BS integrates whole WiFi/BT function blocks into
a chip, such as SDIO/UART, MAC, BB, AFE, RFE, PA, EEPROM and LDO/SWR, except
fewer passive components remained on
PCB.
