Kimera Base: common questions

What microcontroller does the Kimera Base use?

The Kimera Base is built around the ESP32-DEVKITC, from the ESP32 family.

How big is the Kimera Base PCB?

The Kimera Base measures 114.3 × 30.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kimera Base?

2 components, from 2 distinct parts. The full bill of materials is listed on this page.

Where can I download the Kimera Base design files?

From the TheClanLabs/Kimera_Base repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Kimera Base design in my own project?

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

Can I test firmware for the Kimera Base 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.
