ECE445L Lab7Restart: common questions

What microcontroller does the ECE445L Lab7Restart use?

The ECE445L Lab7Restart is built around the ESP32-D0WD-V3, from the ESP32 family.

How big is the ECE445L Lab7Restart PCB?

The ECE445L Lab7Restart measures 150 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ECE445L Lab7Restart?

83 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the ECE445L Lab7Restart design files?

From the Andres-Wearden/Lab10 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ECE445L Lab7Restart design in my own project?

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

Can I test firmware for the ECE445L Lab7Restart 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.
