Core-Board: common questions

What microcontroller does the Core-Board use?

The Core-Board is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the Core-Board?

The Core-Board measures 127 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Core-Board?

27 components, from 17 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 Core-Board design files?

From the calstar/le2-pcb-hardware 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 Core-Board design in my own project?

Yes, under the terms of its CC0-1.0 license, which calstar chose for the repository.

Can I test firmware for the Core-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.
