This repository contains custom firmware for the modified Filco Minila Air keyboard, which replaces the original controller with the n52840nano_v2—an affordable alternative to the nice!nano v2.

To reduce pin usage, the following pin mergers were implemented:

• C0, C14, C15 merged to C0
• C3, C11 merged to C3
• C7, C13 merged to C7
• C10, C12 merged to C10

Additionally, to conserve power, LED pins have been swapped.

The final configuration of the pin map is as follows:

To build the firmware, follow these steps:

git clone https://github.com/QlDoors/minila-nano.git
git clone https://github.com/zmkfirmware/zmk.git
cd zmk
python3 -m virtualenv .venv --python=python3.7.5
source .venv/bin/activate
pip3 install -U west
west build -p -b nice_nano_v2 -- -DSHIELD=minila_nano -DZMK_EXTRA_MODULES="/path/to/minila-nano" -DZMK_CONFIG="/path/to/minila-nano/config"

Replace /path/to/minila-nano with the actual path to the cloned minila-nano directory on your system.
