ESP32-H2-MINI-1: common questions

What microcontroller does the ESP32-H2-MINI-1 use?

The ESP32-H2-MINI-1 is built around the ESP32-C3-MINI-1, from the ESP32 family.

How big is the ESP32-H2-MINI-1 PCB?

The ESP32-H2-MINI-1 measures 50.3 × 60.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-H2-MINI-1?

46 components, from 31 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-H2-MINI-1 design files?

From the 74th/esp32-dev-boards 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-H2-MINI-1 design in my own project?

Yes, under the terms of its MIT license, which 74th chose for the repository.

Can I test firmware for the ESP32-H2-MINI-1 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.
