ECE 445L Baseline Project: common questions

What microcontroller does the ECE 445L Baseline Project use?

The ECE 445L Baseline Project is built around the ESP8266-1, from the ESP8266 family.

How big is the ECE 445L Baseline Project PCB?

The ECE 445L Baseline Project measures 194.9 × 93 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ECE 445L Baseline Project?

61 components, from 41 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 ECE 445L Baseline Project design files?

From the mjetpurwala/SchoolProjects 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 ECE 445L Baseline Project design in my own project?

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

Can I test firmware for the ECE 445L Baseline Project without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
