Rev0: common questions

What microcontroller does the Rev0 use?

The Rev0 is built around the QWIIC_RIGHT_ANGLE, from the ESP32 family.

How big is the Rev0 PCB?

The Rev0 measures 67.3 × 96.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rev0?

125 components, from 34 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 Rev0 design files?

From the Hasatio/WaterQualityControl 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 Rev0 design in my own project?

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

Can I test firmware for the Rev0 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.
