ESP32-Uno-Board v2: common questions
What microcontroller does the ESP32-Uno-Board v2 use?
The ESP32-Uno-Board v2 is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the ESP32-Uno-Board v2?
The ESP32-Uno-Board v2 measures 68.8 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP32-Uno-Board v2?
23 components, from 17 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 ESP32-Uno-Board v2 design files?
From the halherta/KiCadProj 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 ESP32-Uno-Board v2 design in my own project?
The repository has no license, so all rights stay with halherta. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESP32-Uno-Board v2 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.
