ENV-sensor esp32: common questions

What microcontroller does the ENV-sensor esp32 use?

The ENV-sensor esp32 is built around the esp32-s3-wroom-1-devkit, from the ESP32 family.

How big is the ENV-sensor esp32 PCB?

The ENV-sensor esp32 measures 55 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ENV-sensor esp32?

9 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the ENV-sensor esp32 design files?

From the bruvv/ENV-sensor-esp32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ENV-sensor esp32 design in my own project?

Yes, under the terms of its GPL-3.0 license, which bruvv chose for the repository.

Can I test firmware for the ENV-sensor esp32 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.
