 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. |

Anyone used these ? They are apparently pi pico type modules but with a sd micro card socket as well, but I don't know how pico-similar they are. Not expensive though. adalogger |

It looks like you could probably use it with MMBasic as the SD card uses SPI2 with CS on GP23. You may need to use OPTION PICO OFF to do that. I wouldn't have said it was all that cheap though. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

@ zeitfest Thanks Buddy that is Cool as all hell. There are Many Universal Truths That can NEVER be Avoided. The Universal Truth we are concerned with right now is "any Unexpected windfall of cash, will coincide with an equal and opposite unexpected Expense" and zeitfest old buddy you have provided that expense! @ Mixtel90 That would be the coolest Picomite VGA, do you think it's unreasonable to use the reference Circuits in the Picomite Manual to build a series of stackable Hats like one for VGA/KB (and if room maybe sound) - a hat for sound / Real time Clock - and a power hat that will have 2 18650 Batteries with a USB Power/charging circuit?

Do you mean the Serial Node, Rick? That's at an advanced stage now. Battery supply (although I have a problem with that at the moment) Serial Node board (uses Raspberry Pi format & GPIO layout) 8 alternative COMM adapters that can be plugged into it (including isolated COM now) VGA hat with PS2, microSD and PWM sound VS1053 hat to replace the sound section of the above LCD display hat with 1.54" display and 6 buttons The tiny RTC is also supported. I can't fit 2x 18650 with a charger and DC/DC converter into a Raspberry Pi footprint without mounting some of the stuff underneath the PCB. I've tried. :) I'm still thinking about the PSU side.

Can you link me to this Node I'm interested Please, I'm gonna do a search but... I'm dumb Thanks Footnote added 2024-07-18 06:11 by Rickard5 I Found it, Take my Money :) close to my thought I may be Vulgar, but , while I'm poor, I'm Industrious, Honest, and trustworthy! I Know my Place |

Hey man in my messes up vision if the 18650 power board were to part of the stack it would have to the Last bottom board with the Battery compartment a custom printed battery box on the bottom Side so you have most of bit sides of the board for the SMD Logic snd the wider base will make it more gooder, because it will stabilize the stack, too if battery case is removed the power supply is already there :) I may be Vulgar, but , while I'm poor, I'm Industrious, Honest, and trustworthy!

yes looking at it again, it is more expensive than I thought  I am starting to think of a $per-square-cm index for small cards  |
