KeyDuino - The quick & easy way to build NFC enabled things


Keyduino is an Arduino compatible development board with built-in NFC (Near-Field Communication). KeyDuino is the easiest way to build an NFC project with the benefit of  Arduino.

KeyDuino greatly simplifies the development of your NFC projects thanks to the simplicity of Arduino platform. 

KeyDuino will be the bridge that helps you wirelessly interact with your environment, drive motors, unlock strikes, control relays, read from a temperature sensor and all thanks to built-in NFC connectivity, right out of the box.

Hacking is a passion for me, any kind of hacking: hardware, software but also pyrotechnics.

I really like to share my passions through open source projects and you can find some cool stuff on my YouTube channel here.

KeyDuino was my Master’s degree final project and was a great experience based on a Kickstarter.

Arduino CNC Shield – 100% GRBL Compatable

Do it yourself CNC projects are popping up everywhere and we decided that we wanted to contribute to the growth.

Here are a few of our design goals:

  • Modular Design – We wanted to do more than just keep cost down. We wanted things to be reusable and up-gradable. (Arduino, Individual Stepper Motor Drivers and more…)
  • Compact Design – Squeezing a 4 axis design into a board the same size and Arduino Uno.
  • Opensource Software – 100% GRBL compatible (G-Code Interpreter)
  • Evolving Development – We are keen to improve on the design and welcome all feedback.
