$12 Arduboy compatible system

This is my favorite thread in the community, I love seeing all these different ways the hardware is remixed. When people are learning new fabrication techniques and learning about putting these things together for the first time it’s even cooler.

You people are the best! Keep up the good work! Keep hacking and making!


The only reason I was able to create the original Arduboy prototype, or even learn about electronics or hardware was because all of the materials were open source from Adafruit and Sparkfun so I feel it’s the right thing to do to continue sharing and keeping it open. It’s not a traditional business model but I think it creates amazing communities!


Lol what if we just scaled the entire Arduboy size up to match the larger OLED’s Arduboy+? Game system the size of a notepad! haha.


This, by far, is my favorite thread. =D


Do you have the schematics file for your PCB? I’d like to create this.

so all the parts have just arrived for my arduboy clone, but how do i hook up the display to the Arduino Micro? :confused:
Edit: Nevermind, was able to find all the required pins by looking at the library code. It works perfectly! :slightly_smiling_face:


I just stumbled across the Pololu range of 32u4 boards I’ve not had a chance to check what pins are available across the models but they look pretty nifty and the bootloader is opensource.

So it has been 4 Years now Bateske and Arduventure KS is an Amazing success, Backer #608 and had to get the plushie. And now I seriously have to build one of these Arduboys myself. Thank you for the inspiration.


Depends. If you are getting a board similar in PIN(like the Arduino Micro) it will work just fine, not to say a board the Arduboy originated from–Arduino Leonardo.
Just guessing…

yep. It will no problem for micro and leonardo. But Pro Micro is dirt cheap and can be found easily, I can make a few of arduboy to share for my friends and my kid. I have Arduino Micro in hand but I think it can be use for other project and not thinking about buying it anymore because its a bit expensive and also difficult to find in my country

I’ve done that in my new board package. You can use the features (OLED CS, 2nd speaker pin, green LED with PWM) with a Pro Micro.

Not a problem!
I was still the ONLY guy who knows how to solder (one of my friend once soldered something that later on look like a lump of pig-iron.)
Well most Arduinoare cheap anyway (a micro is about the same price as Micro pro, and sometimes you can get Leonardo for even less. ETH costs, though.)

@MLXXXp @FManga
I have viewed this thread and would like to start my discussion for my own case and you closed it?
I know it is the same thing but 385 posts later…really?

What does your display look like?
The only four components beside the Arduboy itself-Screen, button, LED, beeper. I got buttons, LED, beeper, adjustable resistors, resistors, and a circuitry board. And some pins.

And if you can kindly direct me to a place that tells me how to wire all of them, that will be very helpful.

And a search of this topic for “leonardo pin” gives one post with most of the information you need.


These are the displays I’m using:

Here’s my wiring table for Arduboy/Arduinos:

As sugested by @MLXXXp have a search for Leonardo pin you will find lot’s of info on wiring up the hardware. Read it care fully.Take a piece of paper and make some notes /make drawings. Figuring out how to and building your own Arduboy is fun and rewarding.


I thought this but then I realised it’s like s gateway drug and leads to more and harder projects.


I know. I’ve ordered parts to make a 100% solderless breadboard Arduboy. Not doing any soldering is quite challeging i think. Will get some of those transparent mini breadboards. Want to hook up a few RGB LEDs to illuminate them :smiley:


I’ll be using 4 of these transparent mini breadboards and want to light it up more evenly so I probably need more then one RGB LED. Not sure where I’ll be mounting them yet. But I’ll figure it out once I got the parts.

The idea is to put those mini breadboards together in a 2x2 vertical setup so I can put a Arduino micro in the middle of the top two. The 2.4" display will go over the micro with help of some extra pin headers. Bottom two mini breadboards will be mainly used for the buttons.


Hello and welcome to the end! This is the end of the single largest thread of the Arduboy Community!

Welcome to the beginning of the Arduboy Homemade Category!

Please post each new system in it’s own unique thread in the home made category.

(If you have already posted here and would like to make a new thread, that is encouraged! But I’m also looking using the server to create new threads pulling posts out of this one.)

This thread is now closed, happy posting!
