Wiring Connections

Notes:
When wiring, pay attention to the hole position marks on the Futureboard lite. It can only be connected to the two UART ports on the left, and the corresponding position needs to be set in the code. The diagram shows the connection of uart0, and the following code examples are based on this position. In addition, some computers have a small USB current that may not be able to power the koi, resulting in a failure to start. At this time, an external USB power supply can be connected to the koi.
