CM-43438-V1 is a small size and low profile of WiFi + BT combo module with 21-half-holes, board size is 19mm*12mm with module height of 2mm. It can be easily manufactured on SMT process and highly suitable for tablet PC, ultra book, and mobile device and consumer products. It provides SDIO interface for WiFi to connect with host processor and high speed UART interface for BT. The WiFi throughput can go up to 150Mbpsin theory by using 1x1 802.11n b/g/n MIMO technology and Bluetooth can support BT4.1.
CM-43438-V1 uses Broadcom BCM43438, a highly integrated WiFi/BT single chip based on advanced COMS process. BCM43438 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.
