Env sens: common questions

What microcontroller does the Env sens use?

The Env sens is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Env sens PCB?

The Env sens measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Env sens?

36 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Env sens design files?

From the hpvdt/typhoon_electronics 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 sens design in my own project?

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

Can I test firmware for the Env sens 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.
