Robotica: common questions

What microcontroller does the Robotica use?

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

How big is the Robotica PCB?

The Robotica measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Robotica?

52 components, from 23 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 Robotica design files?

From the La-guajolota/Robotica 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 Robotica design in my own project?

Yes, under the terms of its MIT license, which La-guajolota chose for the repository.

Can I test firmware for the Robotica 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.
