The WG3221-00 from Jorjin is a Wireless LAN and Bluetooth Combination Module that supports 1×1 IEEE 802.11a/b/g/n/ac WLAN and Bluetooth 5.0, enabling seamless integration of WLAN/BT and Bluetooth low-energy technology. The WLAN function is connected to the host processor via an SDIO interface, and the Bluetooth is connected via a UART interface. This combo module supports 20 MHz/ 40 MHz channels at 2.4 GHz and 20 MHz, 40 MHz, or 80 MHz at 5 GHz. It also supports Bluetooth 5.0, BLE, ANT+, and is backward compatible with BT 1.x and BT 2.x + EDR.
The WG3221-00 module features BT-WLAN coexistence and ISM-LTE coexistence. This device is based on Qualcomm’s QCA9377-3 chipset and includes an integrated crystal, a power inductor, a filter and a diplexer on a single module. It is available in a 108-pin package that measures 16.0 x 12 x 2.1 mm with single-ended RF port and I-PEX MHF4 connector.
