ESP32: common questions
What microcontroller does the ESP32 use?
The ESP32 is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.
How big is the ESP32 PCB?
The ESP32 measures 25.9 × 64.3 mm, has 4 copper layers and is 1.600198 mm thick.
How many components are on the ESP32?
16 components, from 11 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 design files?
From the SREE-VISHNU-N/PCB_DESIGN 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 design in my own project?
The repository has no license, so all rights stay with SREE-VISHNU-N. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESP32 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.
