KiCad ProjB: common questions
What microcontroller does the KiCad ProjB use?
The KiCad ProjB is built around the ESP32, from the ESP32 family.
How big is the KiCad ProjB PCB?
The KiCad ProjB measures 166 × 166 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the KiCad ProjB?
50 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the KiCad ProjB design files?
From the liyakeselman/Spinning_Top_Real_Time_Platform repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the KiCad ProjB design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the KiCad ProjB 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.
