README
README.mdPICOre 
The PICOre project consist of an ecosystem with stamp modules all pin to pin compatible. This project and product will give you the opportunity to save you time in PCB design and assembly. No need to copy and paste parts of previous design just to have the microcontroller part right. Just drop the picore into your design and that it !
- The PICOre has the necessary USB protections so you will just need to put a USB connector on your project if you wish with differential trace for D+ and D-.
- The GND and AGND are both connected on the PICOre module using star grounding technic so if you need it on your PCB they can stay completely separated.
- The Analog Vref is floating so if you need it you have the choice to connect it with the internal LDO or hook your own vref chip on your design for better result.
RP2040 version
The RP2040 version has all the 30 standard GPIOs you will find on a standard pico. Don't forget to follow the GPIO numbers because all of the others will are not used.
How to use
The files you will need if you want to use the PICOre (of any version) into your PCB project is in the Kicad_Lib folder. Make sure to use and connect pins that are available and not any of them. For exemple the RP2040 version has 30 GPIOs so all the other will not be connected.
There is 3 footprints you can choose. Use the THT version if you want to have easy access to the USB and SWD pin under you PCB and use the SMD version if you want BGA style solder joints. The PCB footprint is for those who wants to create their owm pcb version for other MCU with on the same ecosystem.

Questions
How big is the Stamp RP2040 PCB?
It measures 29.5 × 23.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stamp RP2040 use?
44 parts, built around the RP2040, W25Q16JVUXIQ, AP2112K-3.3 and USBLC6-2SC6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Stamp RP2040 KiCad files?
From the TheContrappostoShop/PICOre repository on GitHub, at the commit this page was made from: the board is V.RP2040/KiCad_File/stamp_RP2040.kicad_pcb and its schematic V.RP2040/KiCad_File/stamp_RP2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stamp RP2040 design in my own project?
Its repository states no licence, so its author keeps all rights: ask TheContrappostoShop before reusing the design.
