Fuente Simetrica: common questions

What microcontroller does the Fuente Simetrica use?

The Fuente Simetrica is built around the ESP32_DevKit_V1_DOIT, from the ESP32 family.

How big is the Fuente Simetrica PCB?

The Fuente Simetrica measures 120.3 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fuente Simetrica?

74 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fuente Simetrica design files?

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

Can I use the Fuente Simetrica design in my own project?

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

Can I test firmware for the Fuente Simetrica 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.
