OpenPrint: common questions

What microcontroller does the OpenPrint use?

The OpenPrint is built around the RP2354A, from the Raspberry Pi family.

How big is the OpenPrint PCB?

The OpenPrint measures 25 × 25 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the OpenPrint?

48 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the OpenPrint design files?

From the dac63701/OpenPrint repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the OpenPrint design in my own project?

The repository has no license, so all rights stay with dac63701. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the OpenPrint without the hardware?

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