Seguidor2021-H: common questions

What microcontroller does the Seguidor2021-H use?

The Seguidor2021-H is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Seguidor2021-H PCB?

The Seguidor2021-H measures 3.7 × 3.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Seguidor2021-H?

20 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Seguidor2021-H design files?

From the erufes/Seguidor2021-H repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Seguidor2021-H design in my own project?

Yes, under the terms of its GPL-3.0 license, which erufes chose for the repository.

Can I test firmware for the Seguidor2021-H 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.
