Prototype Main Board: common questions

What microcontroller does the Prototype Main Board use?

The Prototype Main Board is built around the ESP32-WROOM-32E-N4, from the ESP32 family.

How big is the Prototype Main Board?

The Prototype Main Board measures 80.9 × 66.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Prototype Main Board?

71 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the Prototype Main Board design files?

From the Krypthick/Prototype-Bras-Continuum repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Prototype Main Board design in my own project?

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

Can I test firmware for the Prototype Main 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.
