RFduino Coin-Sized Arduino Microcontroller with Bluetooth 4.0: Small Size, Long Reach

by Lambert Varias

Arduino microcontrollers are beloved by students and hobbyists because they’re affordable, small and versatile. Those are the same exact traits that the RFduino microcontroller possesses. In addition, it has one thing that other Arduino boards don’t have: built-in Bluetooth connectivity.


The RFduino was developed by Open Source RF, an electronics shop that makes Arduino-compatible peripherals and modules. The shop’s tiny invention makes it possible for people to make small gadgets and sensors that can be controlled or monitored wirelessly using a smartphone. You’ll have to buy and then fit a separate wireless shield to an Arduino board to achieve the same functionality.

Speaking of shields, the RFduino also has compatible shields that extend its functionality, including one with a USB-port and another with a coin cell battery slot. It also runs code written in the Arduino programming language, which should really make it an enticing platform for Arduino users. Check out the video below to see how the RFduino can be used:

They should have called it the Fleaduino – a small board with mad reach. Build a Pledge-Bot and pay at least $19 (USD) on the RFduino Kickstarter by April 4, 2013 to reserve your own unit.

    This is really a great work. The standardized stackable boards are hi-end LEGOs to big kids. Just wonder how can we get the RFduino app from the App Store. I could not find it.

    • Hey Daddiest, First of all I don’t think there is a single RFduino do-it-all app. The examples shown above are most likely specialized sketches that only serve one function each, like control a buzzer or notify you that the door is open or closed. Also I’m guessing the apps have not been submitted to the App Store just yet. They’ll probably be released at around the same time that the RFduino is made available to Kickstarter backers. :)

    Hey all I am prototypeing and what i need is a micro controller to go with my force sensor What I’m trying to do is as soon as the sensor feels pressure it will show the results on a small Lcd screen

    I would like to aid. I would like to make a control slide the image that is in the iphone screen by bluetooth. to slide the messages that are on the screen.
