PCB-Files: common questions
What microcontroller does the PCB-Files use?
The PCB-Files is built around the ESP32-S2-SOLO-N4, from the ESP32 family.
How big is the PCB-Files?
The PCB-Files measures 5 × 11.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PCB-Files?
68 components, from 33 distinct parts. The full bill of materials is listed on this page.
Where can I download the PCB-Files design files?
From the Pebblin/PCB-Files repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the PCB-Files design in my own project?
The repository has no license, so all rights stay with Pebblin. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PCB-Files 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.
