Led controller v2: common questions
What microcontroller does the Led controller v2 use?
The Led controller v2 is built around the ESP32-WROOM-32D, from the ESP32 family.
How big is the Led controller v2 PCB?
The Led controller v2 measures 71 × 71 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Led controller v2?
50 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Led controller v2 design files?
From the Roman3349/led-controller-v2 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Led controller v2 design in my own project?
Yes, under the terms of its Apache-2.0 license, which Roman3349 chose for the repository.
Can I test firmware for the Led controller 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.
