A new add-on board that utilizes the USB signal lines of the ODROID-M1S 14-pin expansion header connector. Your M1S is now connected wirelessly with the built-in WiFi module inside the case. It also provides a solution to the limited number of USB ports on the M1S. Other small USB adapters like a wireless keyboard/mouse USB dongle can be embedded into the cases too.

The SMD type 5-pin header socket connector can be easily bent by external force. Therefore, when handling the Internal USB Board or attaching/detaching a USB device, be careful NOT to apply force to the header pin socket. 

The Internal USB board is simply composed of a 5-pin header socket, USB 2.0 host connector, and USB power protection circuit

The WiFi Module 5BK is connected to the Internal USB board

Align it with Pin #1 as shown in the picture below and connect it to the M1S 14pin header
