LED Device: common questions

What microcontroller does the LED Device use?

The LED Device is built around the ESP32S-WROOM-32, from the ESP32 family.

How big is the LED Device PCB?

The LED Device measures 114.6 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LED Device?

14 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the LED Device design files?

From the PJalv/SDP-IoT-Device-Control repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LED Device design in my own project?

The repository has no license, so all rights stay with PJalv. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LED Device 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.
