The Arduboy is a fantastic 8-bit game handheld video game platform built around a Microchip ATmega32U4 micro-controller. It’s open source, and there is a bunch of documentation that will help you build your own games. Since it crowdfunded itself into the retro-gaming scene back in 2015, it has become a staple of the community — and we’ve seen some impressive hacks including a flexible one called the Arduflexboy.
However this might be the smallest one yet, say “Hello” to the Arduboy Mini.
“Arduboy was reconstructed to smallest possible dimensions using the 0.96 OLED. I used TQFP packaging for this one because I thought it would be easier to solder. That chip was but I made a lot of other design choices that made bringing this board up a major pain in the behind. The tight placement of the passive components meant that if there was any problems during reflow it was very difficult to get a soldering iron in…”
“…I omitted ISCP programming pads because I figured it would be fine to program the chip using magnet wire to the pins. This was a terrible and error prone idea. Put programming pads on your board, you are only making your own life more difficult! I also neglected to connect the signal network for the chip select for the external EEPROM memory chip, so I had a little magnet wire bodge on that.”
