ECE445L Starter: common questions
What microcontroller does the ECE445L Starter use?
The ECE445L Starter is built around the ESP32_30pin, from the ESP32 family.
How big is the ECE445L Starter PCB?
The ECE445L Starter measures 164.3 × 114.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ECE445L Starter?
62 components, from 42 distinct parts. The full bill of materials is listed on this page.
Where can I download the ECE445L Starter design files?
From the Andres-Wearden/Lab10 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ECE445L Starter 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 Starter 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.
