Esp32-temp: common questions

What microcontroller does the Esp32-temp use?

The Esp32-temp is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Esp32-temp PCB?

The Esp32-temp measures 57.1 × 56.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-temp?

24 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-temp design files?

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

Can I use the Esp32-temp design in my own project?

Yes, under the terms of its Apache-2.0 license, which angelnu chose for the repository.

Can I test firmware for the Esp32-temp 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.
