Final Project: common questions

What microcontroller does the Final Project use?

The Final Project is built around the ESP32DEVKITV1, from the ESP32 family.

How big is the Final Project PCB?

The Final Project measures 206.4 × 121.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Final Project?

69 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Final Project design files?

From the NikhilMSeb/ECE445-FA21-Solar repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Final Project design in my own project?

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

Can I test firmware for the Final 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.
