The Jorjin WG7831-B0 is a low cost 2.4GHz WLAN + Bluetooth system in package (SiP) module based on the WL1831 SoC from Texas Instruments.  It contains a power amplifier, Tx filter and Tx/Rx switch as well as the necessary passive components to fully implement the 802.11b,g,n WiFi & Bluetooth 4.1 functions.

The WG7831-B0 WLAN is connected to the host processor via a 1.8V SDIO interface, and the Bluetooth is connected via a UART.  Linux and Android drivers are provided for a wide range of application processors, with WinCE and Windows Mobile drivers available from our partner network.

Jorjin can supply a suitable 2.4GHz chip antenna for the WG7831-B0 and can provide complete design services including a  full design review and FCC/CE certification.
