V1: common questions
What microcontroller does the V1 use?
The V1 is built around the CONTROLLER, from the ESP32 family.
How big is the V1 PCB?
The V1 measures 250 × 250 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the V1?
94 components, from 11 distinct parts. The full bill of materials is listed on this page.
Where can I download the V1 design files?
From the antonu17/rgb_led_cube repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the V1 design in my own project?
The repository has no license, so all rights stay with antonu17. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the V1 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.
