Stacklight hardware: common questions
What microcontroller does the Stacklight hardware use?
The Stacklight hardware is built around the ESP32-WROOM-32D, from the ESP32 family.
How big is the Stacklight hardware PCB?
The Stacklight hardware measures 132 × 60 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Stacklight hardware?
115 components, from 63 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 Stacklight hardware design files?
From the Tyler-Ward/stacklight-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 Stacklight hardware design in my own project?
Yes, under the terms of its CC-BY-SA-4.0 license, which Tyler-Ward chose for the repository.
Can I test firmware for the Stacklight 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.
