From the project

This repository is dedicated to the open-source device "Intertidal chamber". Here we'll deposit hardware, firmware and structural instructions.

Intertidal chamber ========================================

The Intertidal Environmental Chamber is a self-contained, automatic experimental system that simulates the intertidal environment. Using multiple chambers, researchers can create “virtual common garden experiments” across large geographic spans. The system plugs into a regular mains power outlet and controls other mains power devices (such as pumps and heaters) and 12 V (such as fans, LEDs, and water valves).

Chamber-DESKTOP-ENIFSN0: common questions

What microcontroller does the Chamber-DESKTOP-ENIFSN0 use?

The Chamber-DESKTOP-ENIFSN0 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Chamber-DESKTOP-ENIFSN0 PCB?

The Chamber-DESKTOP-ENIFSN0 measures 225.6 × 150.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Chamber-DESKTOP-ENIFSN0?

174 components, from 36 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 Chamber-DESKTOP-ENIFSN0 design files?

From the coastalwarming/Intertidal_chamber repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Chamber-DESKTOP-ENIFSN0 design in my own project?

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

Can I test firmware for the Chamber-DESKTOP-ENIFSN0 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.
