Pico Computer 3 – New production run (V3.3?) Hi Peter, hi everyone, I'm planning another production run of the Pico Computer 3, with a minimum quantity of 15 boards. I've noticed that your GitHub repository now contains versions 3.2 and 3.3 in addition to 3.1. According to the README, V3.2 uses a different USB host power controller, while V3.3 also improves the thermal connection of the 1.3V regulator. Before placing the order with JLCPCB, I'd like to ask: Peter, would you recommend using V3.3 for a new production run? Has this revision already been built and tested successfully? I'm planning to use the following files: - PicoComputer3.3.zip - PicoComputer3.3BOM.xlsx - PicoComputer3.3CPL.xlsx Thanks in advance! Best regards, Manfred Added question: What's abot the placement of RMC2. It looks faulty.  Edited 2026-10-21 23:39 by ManiB |

I've built 3.3 and it works perfectly, the keyboard version also uses the same circuit as 3.3. JLC don't have a 3d model for the RMC but the board will be fine. |

Can someone link me to the v3.3 files. I was not aware of progression from v3.1, so for the next lot of boards that I order, I would like to be sure I also am using the v3.3 boards.  I think Peter has them up on Github, but I forget the link....  Smoke makes things work. When the smoke gets out, it stops! |

At the bottom of https://github.com/UKTailwind/Pico-Computer-3 file list there are a couple for v3.3. Perhaps the readme file has the info you need. |

@Grogster You can also find a list of links here in my blog post, including Gerber files for the front and back panels: https://mikrocontroller.bplaced.net/wordpress/pico-computer-3-fertigung-begonnen/ Edited 2026-10-22 16:59 by ManiB |

Manfred, I would like to be added to your order list for a PC3 set. (Just a moment ago I made a request in your blog.) Fred |

Hello Fred, yes, you are on the list now. Shipping costs to Finland are 14,50 €. And thank you for reading my book . I’m really glad that it helped you get back into MMBasic programming. Edited 2026-10-22 23:15 by ManiB |

Thank you for putting me on the list! When can I expect to get the PC3? Getting back into MMBasic was one thing, but getting back into german is more challenging. In 1977 I had my latest exam in german and after that only used the language occasionally. |

Hallo Manfred, einmal in schwarz reizt mich :-) Wenn es noch geht, plane mich für ein PC3 ein. Danke. Viele Grüße Matthias Hi Manfred, I’m tempted to go for black this time :-) If there’s still space, please add me to the list. Thanks. Best regards, Matthias |
