~~All of these changes can be seen (an edited!) in the schematic and the pcb. This was made only for convenience with the wiring. You should recompile the firmware you're planning on use to accomodate for these changes.~~ Reverted back to original Pico wiring! Thanks for the feed

OpenMiniRectangle: common questions

What microcontroller does the OpenMiniRectangle use?

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

How big is the OpenMiniRectangle PCB?

The OpenMiniRectangle measures 245.6 × 150 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenMiniRectangle?

80 components, from 21 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 OpenMiniRectangle design files?

From the quark-works/OpenMiniRectangle 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 OpenMiniRectangle design in my own project?

Yes, under the terms of its MIT license, which quark-works chose for the repository.

Can I test firmware for the OpenMiniRectangle 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.
