MOD-ESP32-C5: common questions

What microcontroller does the MOD-ESP32-C5 use?

The MOD-ESP32-C5 is built around the ESP32-C5-WROOM-1-N8R4, from the ESP32 family.

How big is the MOD-ESP32-C5 PCB?

The MOD-ESP32-C5 measures 20 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MOD-ESP32-C5?

26 components, from 19 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 MOD-ESP32-C5 design files?

From the OLIMEX/MOD-ESP32-C5 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 MOD-ESP32-C5 design in my own project?

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

Can I test firmware for the MOD-ESP32-C5 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.
