ECG Project: common questions
What microcontroller does the ECG Project use?
The ECG Project is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the ECG Project PCB?
The ECG Project measures 56.5 × 47.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ECG Project?
78 components, from 36 distinct parts. The full bill of materials is listed on this page.
Where can I download the ECG Project design files?
From the Vike-n/ECG_Project repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ECG Project design in my own project?
The repository has no license, so all rights stay with Vike-n. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ECG 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.
