Hi, I have the duinotech nano board which I use by plugging into a solderless breadboard. This is ok but cumbersome because its not that easy to plug in. I have the atmega 328p mcu with arduino uno bootloader from jaycar. Easy to plug in.
Also for jaycar next to the mcu is the serial module which I also have. I have seen many articles that say you can use the serial module which has a usb socket to program the mcu.
None of these articles are very clear. Can anybody suggest a good clear article for doing this or else a step by step way to do it.
Thanks.
I’m a bit confused here ..
That nano clone has a usb plug on one side . You can program via that and a PC , presumably like any other nano ?
The clone may have a different usb interface chip , so you might need a driver for that (CH340 USB chip for example )
Or am I missing something ?
SparkFun used to have a clear hookup guide but it seems to have changed; https://learn.sparkfun.com/tutorials/using-the-arduino-pro-mini-33v/all (ignore the fact that it's 3.3V unless that is what you need).
Other one that I found while looking for an alternative tot he SparkFun hookup guide is How to connect an Arduino Pro Mini to a PC via a USB to Serial module | B4X Programming Forum. I can't say if the article is correct but the connection diagram should make clear what is needed.
You will have to check the Pro Mini's schematic diagram and implement the reset circuit on your breadboard.
Lastly you must match the wiring to your FTDU adapter.
I think you're missing that @petercl14 wants to program a bare 328P (that has optiboot).
