Hi! I'm wondering if it could be possible to build a MMBackPack using a RPi Pico? In this case, would MMBackPack documentation apply to the RPi Pico-based BackPack? What are the differences between MicroMite and PicoMite? Do firmwares evolve at the same rate? Thanks, Frédéric |

The two devices are completely different apart from the fact that they both run MMBasic. :) The versions are a bit different though as the Micromite has a lot more limitations. You would need the standard PicoMite documentation for MMBasic. I did a backpack design for a PicoMite some time ago. I think you'll find it if you follow the link in my sig. I've been working on a slight update to it if you are interested. I can't remember offhand whether I've published anything about it yet.

What would you want this backpack to do? A number of people have posted PCBs for the PicoMite. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

The idea is to have a small RP2040-based platform to prototype, with a screen and maybe a few buttons, a battery (+charger), and a speaker, which could run Micropython or MMBasic, and be able to run MMBasic examples written for the MMBackPack... I guess only inits should match the board (pins to LCD)? Frédéric |

I found your design, thanks! Frédéric |

What you described sounds a bit like Toms GameMite design. Screen, a few buttons, speaker (but mono), battery & charger. It's designed for MMBasic, but I suppose you could put Micropython if you mess about enough. It also has a little GPIO port to give a few IO. I haven't done a design with screen and battery so far, mostly because it means buying batteries. :) I've found my version 1.2 of the backpack board. As I said, it adds a few features and tidies up some problems on the original. I didn't do a manual and BOM for it though, although I have a circuit diagram.

I was also going to say it sounds like you might want to consider a Game*Mite. @bigmik and I tried to make the GPIO accessible and I know that @Volhout has been making use of his beyond it's original gaming purpose.
