PiezotesterV2.1: common questions

What microcontroller does the PiezotesterV2.1 use?

The PiezotesterV2.1 is built around the CH340C, from the ESP32 family.

How big is the PiezotesterV2.1 PCB?

The PiezotesterV2.1 measures 119.3 × 97.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PiezotesterV2.1?

49 components, from 27 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 PiezotesterV2.1 design files?

From the JakubJasiejko/PiezoTester_V2.0 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 PiezotesterV2.1 design in my own project?

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

Can I test firmware for the PiezotesterV2.1 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.
