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
When viewed from above the board, it looks like the picture below
There is no internal interference, so it can be used with the top case assembled
