Introduction

This page is to provide information on the Nano v3.0. This is a different device to the model Nano Every as it uses the ATMega328 chip

Getting the ATMega328PB to work

When you buy a Nano v3.0 off some stores you actually got a device which has a ATMega328pb chip. You can tell this because the chip has it written on it.

Using the board with the Ardiuno boardmanager failed for both bootloader options it provides. An example of failure

avrdude: stk500_getsync(): not in sync: resp=0x00

So you need to burn a new bootloader. To do this you need

a working arduino board
your broken board
understanding of the pinout on nano

When I did this the second time Dec 2024 I neglected to understand the pinout for the nano.

This picture suggested the 5v was bottom left of the board. Inspecting the board I found that the connector pictured was upsidedown
So here is how to wire them

Arduino without   |  Arduino as ISP
   bootloader     |   programmer
__________________|________________
ICSP pin#1 (MISO) |      D12
ICSP pin#2 (+5V)  |      5V
ICSP pin#3 (SCK)  |      D13
ICSP pin#4 (MOSI) |      D11
ICSP pin#5 (RST)  |      D10
ICSP pin#6 (GND)  |      GND

Next you need the MiniCore board manager installed.

The plan is to use the working board to download the bootloader onto the nano. To do this go to the examples menu in Arduino IDE and get the ArduinoISP sketch. Now we configure the board manager from MiniCore.

For me these were the settings (except for the port). The important bits were

Board in the Minicore
Port is the port of the ArdiunoISP not the broken board
Programmer is Ardiuno as ISP

And finally a picture of success.

When we go into vs code the minicore settings are available.

-But this still failed but is required. This fails because we need to replace the bootloader. To do this you need another device. In my case I used a Arduino Nano Every. You need to build the ArduinoISP on the working device and wire the two devices together as follows.

-For me I had seen an example where the UART was UART1 (ATMega328PB Only) but this is referring to the host not the target. I did use the wrong value and it did look like it worked (Two red lights, one blinking) but it hadn't. And finally a picture of success.<br>
