Orpheus32: common questions

What microcontroller does the Orpheus32 use?

The Orpheus32 is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Orpheus32 PCB?

The Orpheus32 measures 33 × 51.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Orpheus32?

27 components, from 16 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 Orpheus32 design files?

From the pizzalover125/orpheus32 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 Orpheus32 design in my own project?

The repository has no license, so all rights stay with pizzalover125. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Orpheus32 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
