 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Hello :) This ended now in prototyping and building a showcase. It was not my intention and I could not completely foresee, that it would fit that well.. I mean the whole outcome: It is ALL pin out, really all! I could easily solder the remaining probe connections to the lower row to make it complete and I would bring GP1 as high freq input to the outside. It is very robust and compact and offers everything I can think of. The audio could be replaced by a I2S, the space is sufficient. The PGA2350 is a great design for me. All kind of firmwares available for 2350 can be used and make sense and is suitable for almost every interest. This is again dedicated to us all. Take one or the other idea maybe and I hope again that I could give some inspiration. It was also my way trying to contribute.. All the best to All of you! :) |

Just a concept and it's all about the form factor and versatility. I've seen now all work from everybody. It's an old keyboard for oldschool pads but feels like a lenovo. I will make it completely foldable. I took the time and made it work in full extend and the audio sounds and works superb!! Cheers!  |

Hello again :) I have said this is my last tinkering..don't know but I wanted to finish that. The build works really excellent stable, the audio quality is very nice. So here is the last? chapter. I have drawn a layout some days ago and I will finish this in the way I started. I don't design first and then do it but while I'm drawing the first print is already running :)) Many people have many different thoughts what could be done with PicoMite, here are mine. This could be an educational platform or just for fun. It is all pinout, all firmware and multipurpose :) PGA2350, SD, Audio, RTC, USB, Hub, ILI9341, HDMI and VGA. I'll make it switchable. It's A5 size, the paper underneath is A4.  pico_lab_freecad.zip Reality:   Edit: the free space on the right needs to be filled..thoughts? :) Edited 2025-10-31 04:37 by dddns |

This is my latest work on this. The layout for the breadboard part is completely reworked.. The last parts I found are some 20year old switches I used for a Linux project which I have torn apart. The grey is empty and I'll use last few meters of black. Mad Max from the scratch..I'll try to get it done :)  pico_lab.zip  Switches are 6x on/on fromAugat |
