The KiCad project lives in the bhumijainn/-ESP32-using-KiCad repository on GitHub; these links point at the commit this page was built from.

-ESP32-using: common questions

What microcontroller does the -ESP32-using use?

The -ESP32-using is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the -ESP32-using PCB?

The -ESP32-using measures 151.1 × 100.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the -ESP32-using?

40 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the -ESP32-using design files?

From the bhumijainn/-ESP32-using-KiCad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

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

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

Can I test firmware for the -ESP32-using 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.
