Hello. I ordered this pcb from here. https://pl.aliexpress.com/item/1005008404804398.html?aff_fcid=462c03b2748148e6b5581318d53135f1-1741081937572-06119-_oofC5PP&tt=CPS_NORMAL&aff_fsk=_oofC5PP&aff_platform=shareComponent-detail&sk=_oofC5PP&aff_trace_key=462c03b2748148e6b5581318d53135f1-1741081937572-06119-_oofC5PP&terminal_id=37e83931330948c2abe9075449702469&afSmartRedirect=y&gatewayAdapt=glo2pol https://www.cnx-software.com/2025/02/03/tiny-weact-rp2350b-core-board-exposes-all-48-i-os-from-the-raspberry-pi-rp2350b-microcontroller/ I wonder if it will work on all pins. PS Sorry for my English, but I'm old enough to use a translator. Best regards. |

It will probably meet the Raspberry Pi specification. I wouldn't take any bets on it exceeding the specification though. Personally I wouldn't buy one until I had the schematic. Edited 2025-03-04 23:01 by Mixtel90 Mick Zilog Inside! nascom.info for Nascom & Gemini |

it's actually enough for this https://pl.aliexpress.com/item/1005008404804398.html Edited 2025-03-04 23:07 by guma1975 |

Schematic shows USB-C. At first, I thought it was micro-USB. RP2350B_SCH.pdf |

Sensible people. They put PSRAM CS on GP0 and the LED on GP25. Mick Zilog Inside! nascom.info for Nascom & Gemini |

I really like the layout of this WeAct as there is no need to route the traces on a PCB through the pins. It only lacks on having the bootsel broken out and that it has no PSRAM by default (but you can easily solder it). The best layout (for Hobbyists) is Peters 64-pin dual-in-line RP3250B development board Too bad that it wont't be produced, but hope dies last @guma1975 Please report back when you got it how overclocking works. |

Who says it won't? There is some demand for a RP2350B wired to pins that is breadboard friendly. No other implementation has done that so far. It just needs someone to see it and decide to back it. Mick Zilog Inside! nascom.info for Nascom & Gemini |

In my opinion, this would be a real springboard for the work conceived and done by Geoff Graham. And the community could support this version and not go crazy supporting 1000 versions of the firmware. What do you think? Ronny |

Perhaps you should read into the subject more before pontificating. There aren't 1000 of versions. There are versions supporting RP2040 vs RP2350, VGA vs HDMI vs LCD, Web vs Bluetooth vs neither. All of these are in general H/W agnostic and can be configured by the user to suit a wide variety of boards with different pinouts. |

Ronny: MMBasic on the Picomite is *specifically designed* to be able to run on varied hardware. Yes, you could make a single version, but that would rule out all future hardware development unless you kept producing new versions of MMBasic. If you want a single MMBasic file then I suggest that you get a Pico Computer 3 board (or my own PC3x DIY modular design which is more or less functionally the same). You can then configure everything automatically using a single OPTION command. There is no problem in producing your own hardware that is incompatible with the Pico Computer 3. It's just a little more involved in configuring it. MMBasic is very flexible. Such hardware may be optimised for a particular task. Mick Zilog Inside! nascom.info for Nascom & Gemini |

A reliable board. I just bought 10 of them. The size reminds me of the Intel 486. WeAct PSRAM CS is connected to GP0. Perhaps the PSRam option can also be set to GP0. If not—no problem—remove R14 and connect the solder pad to GP47, and the PSRAM will work. This is described several times on the forum. RM2 Wi-Fi module. Connect the GP23, GP24, GP25, and GP29 to the RM2. To ensure the board runs without a reset, you’ll need to remove the zero-ohm resistor on the WeAct board (see photo).Firmware Webmite 7.0.00B8 works without any patches, etc., without any problems.
