1. Unbox and connect the board to RS232 (COM) port. Here I’m using FTDI USB serial adaptor. Do not plug in the power yet.
2. Open your terminal program and set up as follows:
Baud rate: 115200
Flow control: none.
Here I’m using Teraterm.
3. Plug in power. You should see messages from your terminal program. Hooray! You’re ready to go!
