#Manually Uploading HEX files and setting Fuses on ATmega328

First, the .hex files provided are only for tests purpose as the recommended method is to use Compiling and Programming.

There are many different options to upload a .hex firmware file to the MULTI-Module and to set the correct fuses. This document outlines an approach that uses a USBASP programmer and which is equally compatible with OSX, Windows and Linux operating systems.

1. Follow this section: Install the Arduino IDE
2. Make sure to write down the location of your installation since you need to know where avrdude is installed to configure the AVR8 Burn-O-Mat. For example on a default windows installation, avrdude.exe is located in "C:\Program Files (x86)\Arduino\hardware\tools\avr\bin" where "C:\Program Files (x86)\Arduino" is the installation path.
3. Follow this section: Material you need to upload the firmware
4. Follow this section: Connect the programmer
5. Install AVR8 Burn-O-Mat which is available for all platforms. Installation instructions are on the software page (Don't forget to install Java as explained).
6. Launch AVR8 Burn-O-Mat.
7. You should now have a window which looks like this:
8. click on Settings->AVRDUDE and fill in the details about avrdude location using the installation path written previously as well as selecting USBASP for the programmer:

Fuse settings

Here are some fuse settings for common configurations:

Board	Low Fuse	High Fuse	Extended Fuse
Banggood 4-in-1 module	0xFF	0xD3	0xFD
Arduino Pro Mini	0xFF	0xD3	0xFD
DIY 2.3d PCB	0xFF	0xD3	0xFD
DIY 2.3d PCB with custom mikeb bootloader	0xFF	0xD6	0xFD
Banggood 4-in-1 module with custom mikeb bootloader	0xFF	0xD6	0xFD

If you don't know the 1st line is the one you want.
