eduArdu is new Open Source Hardware educational board targeting kid’s digital education


Few weeks ago we got contacted by Digital Kidz an non for profit foundation which goals are to support digital literacy and innovative education in the schools. They needed hardware board, which to be easy to use and to allow entry level programming with Scratch and Arduino for beginners. They were ready to pay for the development, but we liked the idea and decided to design one such board for free and release it as Open Source Hardware.

The result is here:


The design is based on ATmega32U4 which is easily programmable with Arduino IDE. We named it “eduArdu” as this is educational board programmable with Arduino.

eduArdu has these features:

  • USB connector for programming and power supply
  • red LED matrix 8×8 which allow text and small image animations
  • X-Y Joystick with push button for navigation
  • Microphone for Audio sensing and interactions
  • Speaker for Audio output
  • Light sensor with LDR
  • Digital temperature sensor
  • Status LED
  • IR remote control LED and receiver to talk to other boards, TVs, Air conditioners, etc.
  • PIR motion detector up to 6 meter range
  • UltraSound distance measurement sensor
  • Two SERVO motor connectors (to build easily two wheel robot car)
  • LiPo charger so the whole board may work on LiPO power
  • 6 Makey-Makey style buttons
  • UEXT connector for additional modules


The board is shaped like Game console. The first prototypes will be ready in 2 weeks.

Target sale price is EUR 15.00

    Yeah, cool!
    Do you think that it would be possible to offer a DIY-Soldering kit for this? Or is the LED matrix or any other part BGA?

      there is no BGAs, but the boards has lot of components and not sure it will be easy for beginners to solder it, also to lower the cost components we used are in 0402 packages which are not very hand soldering friendly

    Really cool!

    Very nice ! LiPo could be dangerous with kids, do you think a Power jack version will be also available ?

      Why have a separate power jack, the USB connector is commonly found in the household and does the job of powering such things nicely 🙂

      Yes, indeed LiPo could be dangerous for little kids, but it’s necessary if you want to build Robot car with servo motors (one of the intended app). Battery is not included by default so kid supervisor may decide if to add LiPo or not.

    Great idea (and board)!
    Maybe you could find some free spot to etch a capacitive touch sensor or two on the PCB? I guess the Makey-Makey pins can deal with the touch input but it is always easier to have something onboard (not needing to attach extra wires).

    Sounds much like a souped up version of the Bayduino,doesnt it?

    It is a really nice board! Maybe next version will came with a oled display?

    How many units do you need to get the 15€ price target?

    Great idea, are there any boards produced already or it’s still in production?

    Great work with your EduArdu, congratulation!
    It’s very good, If OpenHardware and OpenSource Software is used in Education 🙂
    It would be a pitty If it is not possible to Code EduArdu with Scratch 3.0 😦
    … and only „big Players“ (like LEGO) could have Extensions 😦
    What about this Scratch Arduino Extension:
    … could it be possible, that it works with EduArdu?

    Best wishes from Germany!
    We hope, that we can install also an education-community in Germany, we will introduce the EduArdu in our school projects – and will show it on the MakerFaire Hannover at our Workshops on August. 18th (together with the MAKE Magazin 🙂
    – please add some PR Material to our Order (FLyer, post-it’s )… it would be nice to have more Projects and Examples for Projects … Even the Use as a kind of MakeyMakey Device is very interesting for Educational Projects!
    … and the robo-Kit is wonderful!
    Keep on develloping such Great openHardware Devices !
    We Need it!
    Best wishes from Germany!
