Aquarius plus: common questions

What microcontroller does the Aquarius plus use?

The Aquarius plus is built around the ESP32-S2-SOLO-N4R2, from the ESP32 family.

How big is the Aquarius plus PCB?

The Aquarius plus measures 167 × 115 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Aquarius plus?

210 components, from 57 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 Aquarius plus design files?

From the fvdhoef/aquarius-plus 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 Aquarius plus design in my own project?

Yes, under the terms of its MIT license, which fvdhoef chose for the repository.

Can I test firmware for the Aquarius plus 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.
