Distribution Board V2: common questions
What microcontroller does the Distribution Board V2 use?
The Distribution Board V2 is built around the ESP32, from the ESP32 family.
How big is the Distribution Board V2?
The Distribution Board V2 measures 206 × 202 mm, has 2 copper layers and is 1.58 mm thick.
How many components are on the Distribution Board V2?
48 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Distribution Board V2 design files?
From the saadmaziz/UoG_TDP_EE3_Team-7_2025-26 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Distribution Board V2 design in my own project?
Yes, under the terms of its MIT license, which saadmaziz chose for the repository.
Can I test firmware for the Distribution Board V2 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.
