V3sDevBoard: common questions
What microcontroller does the V3sDevBoard use?
The V3sDevBoard is built around the ESP32-WROOM-32, from the ESP32 family.
How big is the V3sDevBoard PCB?
The V3sDevBoard measures 100 × 85 mm, has 4 copper layers and is 1.5842 mm thick.
How many components are on the V3sDevBoard?
163 components, from 74 distinct parts. The full bill of materials is listed on this page.
Where can I download the V3sDevBoard design files?
From the sentoxo/V3sDevBoard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the V3sDevBoard design in my own project?
Yes, under the terms of its MIT license, which sentoxo chose for the repository.
Can I test firmware for the V3sDevBoard 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.
