ECG tregatti tech Project: common questions

What microcontroller does the ECG tregatti tech Project use?

The ECG tregatti tech Project is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the ECG tregatti tech Project PCB?

The ECG tregatti tech Project measures 55.9 × 121.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ECG tregatti tech Project?

147 components, from 40 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 ECG tregatti tech Project design files?

From the tregatti-tech/ESP32ECG repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ECG tregatti tech Project design in my own project?

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

Can I test firmware for the ECG tregatti tech Project 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.
