SD-board pico: common questions

What microcontroller does the SD-board pico use?

The SD-board pico is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the SD-board pico?

The SD-board pico measures 100 × 135 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SD-board pico?

51 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the SD-board pico design files?

From the Lintaroh/OMA68k repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SD-board pico design in my own project?

Yes, under the terms of its MIT license, which Lintaroh chose for the repository.

Can I test firmware for the SD-board pico 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.
