About the Front Panel PCB
Front Panel is an open source PCB design by coastalwarming, published on GitHub. It is a 2-layer board measuring 214 × 82 mm, with 38 components from 9 distinct parts.
Other key parts include the MCP23017. By type, the board carries 15 resistors, 10 diodes, 9 switches, 2 connectors, 1 IC and 1 capacitor.
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).

Front Panel: common questions
How big is the Front Panel PCB?
The Front Panel measures 214 × 82 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Front Panel?
38 components, from 9 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 Front Panel design files?
From the coastalwarming/Intertidal_chamber 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 Front Panel 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.
