Esp32-dev board: common questions
What microcontroller does the Esp32-dev board use?
The Esp32-dev board is built around the ESP32-WROOM-32, from the ESP32 family.
How big is the Esp32-dev board?
The Esp32-dev board measures 25.9 × 55.9 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the Esp32-dev board?
28 components, from 18 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-dev board design files?
From the noahwhite07/esp32-dev-board 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-dev board design in my own project?
The repository has no license, so all rights stay with noahwhite07. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp32-dev board 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.
