Picocart64 v2: common questions

What microcontroller does the Picocart64 v2 use?

The Picocart64 v2 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Picocart64 v2 PCB?

The Picocart64 v2 measures 105 × 60 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Picocart64 v2?

152 components, from 33 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Picocart64 v2 design files?

From the khill25/Dreamdrive repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Picocart64 v2 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Picocart64 v2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
