Monolith: common questions

What microcontroller does the Monolith use?

The Monolith is built around the ESP32-S3-WROOM-1-N4, from the ESP32 family.

How big is the Monolith PCB?

The Monolith measures 96 × 74.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Monolith?

112 components, from 37 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 Monolith design files?

From the luftaquila/monolith 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 Monolith design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Monolith 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.
