BaseLine: common questions
What microcontroller does the BaseLine use?
The BaseLine is built around the ESP32-WROOM-32UE_M113EH6400UH3Q0_, from the ESP32 family.
How big is the BaseLine PCB?
The BaseLine measures 108.2 × 131.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the BaseLine?
108 components, from 53 distinct parts. The full bill of materials is listed on this page.
Where can I download the BaseLine design files?
From the smvumbaco/BaselineTech-FA24 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the BaseLine design in my own project?
The repository has no license, so all rights stay with smvumbaco. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BaseLine 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.
