Esp demo: common questions

What microcontroller does the Esp demo use?

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

How big is the Esp demo PCB?

The Esp demo measures 57.5 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp demo?

12 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp demo design files?

From the 1ln/esp_demo_pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esp demo design in my own project?

The repository has no license, so all rights stay with 1ln. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp demo 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.
