We Are Live!

The time has come. Crowdfunding for microByte has begun!

There’s a lot more detail on our campaign page, but a good summary never hurts, right? So here we go. MicroByte is a portable, hand-held, retro-gaming console that allows you to play your favorite NES, GameBoy, GameBoy Color, Game Gear, and Sega Master System games. But it’s not just for gaming. microByte is fully Arduino compatible, so you can also create your own applications. You can even load them onto a microSD card and launch them without reflashing the device!

The whole thing fits in a 7.8 x 4 x 1.7 cm package that’s small enough to fit in your pocket but large enough to keep your hands from cramping. We chose the 1.3" IPS display for its crispness and fabricated the controls using materials that your thumbs will actually enjoy touching. And, with four colors to choose from, it’s adorable as well.

And best of all, microByte is fully open source. Whether you want to modify the firmware, create a custom enclosure, or tweak some other aspect of the device, we invite you to have at it!

So come have a look. And stay tuned, because we’ll be posting some interesting updates over the coming weeks, including one about a MicroPython library that you can use to create your own games!
