ESP32-DevKit-Lipo: common questions

What microcontroller does the ESP32-DevKit-Lipo use?

The ESP32-DevKit-Lipo is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the ESP32-DevKit-Lipo PCB?

The ESP32-DevKit-Lipo measures 27.9 × 48.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-DevKit-Lipo?

47 components, from 33 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-DevKit-Lipo design files?

From the rompasaurus/dilder repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ESP32-DevKit-Lipo design in my own project?

The repository has no license, so all rights stay with rompasaurus. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32-DevKit-Lipo 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.
