Ortho113: common questions

What microcontroller does the Ortho113 use?

The Ortho113 is built around the RP2350_STAMP_XL, from the RP2040/RP2350 family.

How big is the Ortho113 PCB?

The Ortho113 measures 3.7 × 3.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ortho113?

350 components, from 12 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 Ortho113 design files?

From the Montana1176/Lefty-Ortho-113 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 Ortho113 design in my own project?

Yes, under the terms of its MIT license, which Montana1176 chose for the repository.

Can I test firmware for the Ortho113 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.
