The Raspberry Pi RP2040 is the first microcontroller designed in-house at Raspberry Pi (Raspberry Silicon). Initially only available onboard the Raspberry Pi Pico, it is now available to buy as a standalone microprocessor chip for your own home-made RP2040 PCB designs, industrial applications and more – in handy packs of 5. The RP2040 microcontroller comes in a QFN-56 package. The recommended PCB footprint can be found in the datasheet (or see the image below in the Resources section. We are now stocking the latestRP2B2 version. We also stock the Raspberry Pi RP2350A and RP2350B. Sold in a pack of five.
