Smartdisplay hardware: common questions

What microcontroller does the Smartdisplay hardware use?

The Smartdisplay hardware is built around the ESP-32S, from the ESP32 family.

How big is the Smartdisplay hardware PCB?

The Smartdisplay hardware measures 83.2 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smartdisplay hardware?

46 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Smartdisplay hardware design files?

From the BearLaboratory/smartdisplay-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Smartdisplay hardware design in my own project?

Yes, under the terms of its GPL-3.0 license, which BearLaboratory chose for the repository.

Can I test firmware for the Smartdisplay hardware 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.
