Idk pad: common questions

What microcontroller does the Idk pad use?

The Idk pad is built around the ESP32-C3, from the ESP32 family.

How big is the Idk pad PCB?

The Idk pad measures 140 × 79.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Idk pad?

41 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Idk pad design files?

From the idksarah/idk-pad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Idk pad design in my own project?

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

Can I test firmware for the Idk pad 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.
