Aquarium: common questions

What microcontroller does the Aquarium use?

The Aquarium is built around the ATMEGA8A, from the AVR/Arduino family.

How big is the Aquarium PCB?

The Aquarium measures 96.3 × 98 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Aquarium?

71 components, from 49 distinct parts. The full bill of materials is listed on this page.

Where can I download the Aquarium design files?

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

Can I use the Aquarium design in my own project?

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

Can I test firmware for the Aquarium without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
