ThePreamp-Controller: common questions

What microcontroller does the ThePreamp-Controller use?

The ThePreamp-Controller is built around the ESP32-DEVKIT-V1, from the ESP32 family.

How big is the ThePreamp-Controller PCB?

The ThePreamp-Controller measures 336 × 44.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ThePreamp-Controller?

25 components, from 21 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 ThePreamp-Controller design files?

From the Gninnorg/ThePreamp 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 ThePreamp-Controller design in my own project?

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

Can I test firmware for the ThePreamp-Controller 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.
