[] Use the delivered circuit board. Press the start button. When pressing the start button, connect the USB to the computer. Release the start button. Upload the code. The code will not start immediately after downloading. Nothing will happen. Unplug the circuit board and reconnect to the USB. The development board will now guide the code. Connect the motherboard from USB to the computer and connect it to another power source, such as a LiPO battery. The chessboard will start encoding again. This computer is no longer needed.

By performing steps 1 or 2, new code can be loaded onto the circuit board. Both will continue to work.
