2025-03-23 This post shares the story of the nice!nano ; a wireless, Pro Micro-compatible microcontroller board I made in my freshman year of college. The nice!nano powers tens of thousands of keyboards, has inspired many, and changed my life. Over my first winter break in college, I created what I called the Dissatisfaction65 , a wireless 65% keyboard inspired by the Satisfaction75. I don’t remember exactly why, but I wanted to try making a DIY wireless keyboard after having made a few wired ones. The Adafruit 32u4 Bluefruit LE microcontroller was used to accomplish wireless since the open-source QMK keyboard firmware supported Bluetooth with this specific board. The project looked great in the end, but its performance was awful . The typing latency was nearly unusable, and it only lasted a few days on battery even with a huge battery inside. Seeing all the low-latency, long battery-life wireless products from companies like Logitech and Apple, I knew that something better was possible.…
