IMU-ESPC3-Board: common questions

What microcontroller does the IMU-ESPC3-Board use?

The IMU-ESPC3-Board is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the IMU-ESPC3-Board?

The IMU-ESPC3-Board measures 59.5 × 25.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IMU-ESPC3-Board?

54 components, from 34 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 IMU-ESPC3-Board design files?

From the Pledoge/IMU-ESPC3-Board 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 IMU-ESPC3-Board design in my own project?

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

Can I test firmware for the IMU-ESPC3-Board 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.
