LoremIpsum36: common questions

What microcontroller does the LoremIpsum36 use?

The LoremIpsum36 is built around the RP2040_Zero, from the RP2040/RP2350 family.

How big is the LoremIpsum36 PCB?

The LoremIpsum36 measures 236.5 × 111 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LoremIpsum36?

73 components, from 3 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 LoremIpsum36 design files?

From the penk/LoremIpsum36 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 LoremIpsum36 design in my own project?

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

Can I test firmware for the LoremIpsum36 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.
