I have two Nano boards, but the first one seems the CH340 chipset was burn. :( ,
- Nano v3, CH340 chipset but unable to identify after connect to my Mac using USB
- Nano v3, FTDI chipset and in good condition
- USB to Serial module, using FTDI chipset
I am trying to upload a sketch via a USB-to-Serial module OR another Nano board (or UNO board v3) to my CH340 Nano Board.
- How to wire them up?
- Is it need upload a "Arduino as ISP" first?
- step-by-step tutorial or website talking about this ??
