posted is stripboard ok? it works. pcb needs populating and soldering. how many boards needed? I guess not many wave a soldering iron around. it's easy. try "diy layout creator". not knocking pcb just vero quick pcb is good for vga and hdmi sockets that don't fit vero.

There are a few things I don't like about stripboard. 1. Many components won't fit because they are either metric or a silly size - usually about half a hole out. Some, like USB connectors, stand no chance. 2. Old stock stripboard is sometimes a bit of a pain to solder to and needs a good clean before you start. 3. There are no enclosures that are the right size to fit components that align on the front and rear panels because all enclosures are metric or a silly size. 4, The usual problems at high frequency. You can't have a groundplane. 5. Related to 4, loss of a groundplane means that all GND wires have to be wired. 6. Current carrying capacity is a bit limited unless you solder wire along the strips. 7. Poor load-bearing. Try mounting transformers on it. Probably several more! I use it, but I'm starting to use it less now than I used to. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Mick Sir, that's why I used a hdmi breakout board with inbuilt resistors. hdmi socket on vero don't fit. the pico fits. 1 fair enough 2 pcbs need polish? 3 ER design your own 4 c'mon is it a problem 5 true, do they. I use one as the devices common it like pico or ssd or usb to ttl converter and no probs 6 got to be more than thin pcb lines...etched in China? 7 you jokin? what size? |

don't make pcb, no design your own board as easy as possible. it will a one off so pcb is ott, imho it's less hassle than pcb. though not criticising pcb ,it's brill but for pico can be done on "vero" and point any real problems please. making pcb seems fun,still use fecl?

Found it, thank you Peter.  Unfortunately, the Olimexboard did not include a description or circuit diagram, hence the question 'no comment |

Which board is it? Usually they provide both :) John |

Thanks a lot to all contributors of this thread! I am a newbie in PicoMite and with the help of this thread i got my tiny boot to BASIC computer working with this Olimex board and a Pico 2 (RP2345). However i have four questions: 1. i could not find any documentation of the Olimex board, just the circuit diagram. Does any of you have a link for me or even the document itself? 2. i got the btb computer working with the pico 2 and the Olimex board. Is it possible to use a pico 2 W to get some network connection? 3. do you have any recommendation for a really tiny keyboard (wireless, not bluetooth) to connect with the Olimex btb Computer? 4. are there any free 3D print files available for the Olimex board with a Pico 2 on it? Could not yet find any in the web. Thanks for any advice! Best regards Christian Edited 2025-04-02 19:02 by Xian |

Hi Christian, 1. What kind of documentation are you missing? Actually, everything is right here: https://github.com/OLIMEX/RP2040-PICO-PC 3. I have a very small wireless keyboard here - but I first have to test whether it works with the device... 4. Where do you come from? I lasered this housing at FabLab here. I may still be able to get hold of the data:  Frank UPDATE: I have just tested the keyboard - IT WORKS!!! It is a MEASY RC8 and is available here, for example: https://botland.de/eingestellte-produkte/3230-kabellose-tastatur-measy-rc8-smart-touchpad.html  Edited 2025-04-02 20:24 by Frank N. Furter |

Hi Frank, thanks for your information. I'll have to read through the source code to understand better. As it is open source hardware and software, we all can contribute. Let's see - i only just started with PicoMite. The keyboard looks exactly like that, what i am looking for. Thanks for the link. I am living a bit south to Münster - from your nickname i assume you're close to the river Main. If you could send the data for the case, that would be very kind. I'll see if i can find a fablab close to my home town. Thanks! Thanks again for your efforts! Best regards, Christian |

Not really! I live near Nuremberg.  It will take a little while. I have to contact someone first (I should have taken the data with me when I helped design the housing...). I would also like to have a few of the housings laser cut again. Frank Edited 2025-04-02 23:41 by Frank N. Furter |

whoo. i was in Nuremberg last year around end May for the "Fränkisches Bierfest". not sure i can make it this year. But i will let you know. no problem - i'll be patient. If you let some housings laser, let me know. I'm interested, too. Thanks and best regards, Christian |

Hey There, and just another question regarding the Olimex board. Has someone already implemented a real time clock with a backup battery? Are there any recommendations for a certain hardware module together with the Olimex board? I have found a DS3231 module which communicates via I2C bus. That can be attached at the according UEXT pins on the Olimex board. Any advice welcome. thanks and regards Christian |

There are two RTC modules from Olimex: https://www.olimex.com/Products/Modules/Time/ |

We definitely have to meet up when you're in the area again! I live here in Hersbrucker Schweiz - there is quite a high density of breweries here. I am currently trying to get the data... I would also like to connect an RTC to my board. Unfortunately, the original OLIMEX RTC is too big for my housing and would be stuck vertically on the UEXT. I would like to use a different clock and simply connect it to the port. The assignment of the UEXT is well known... Frank |

The little square modules with a built-in yellow battery would be fine. They should be considered as disposable though unless you don't mind fitting an external battery later. I regard them as very hackable as you can even get the connector off them if you are careful. :) There is one spare way on it that I use for connecting an external battery when the original has gone flat. Get a DS3231 type anyway, no matter what shape or size, as they will give you the best results, far better than the PCF ones. I think they are all I2C so you shouldn't have a problem connecting them.

Christian, The blue DS3231 from China with 24C32N EEProm and CR2032 button cell fits perfectly on the bottom of the Olimex HDMI print with 3mm nylon spacers for some extra space for the holes. Greetings, Jan. |
