# ErgoDox-EZ
|
|
|
|
[ErgoDox EZ](https://ergodox-ez.com/) LED mod to convert your regular ErgoDox EZ into an ErgoDox EZ shine.
|
|
|
|
## Instructions
|
|
|
|
To build this mod you need to assemble two LED strips, and one I2C bridge. The LED strips are installed on both sides. The right hand LED strip is directly connected to the main PCB. The left hand LED strip requires an I2C bridge to function.
|
|
|
|
## Firmware
|
|
|
|
Once you've connected your Atmega168 you can compile the firmware and flash your microcontroller with the included makefile:
|
|
|
|
```
|
|
$ make build
|
|
$ make flash
|
|
```
|
|
|
|
The makefile is setup to use the AVR ISP MKII.
|
|
|
|
## LED strip
|
|
|
|
You will need to LED pcbs to build this mod. The LED strips are identical for both sides.
