WLED PCB D1 Mini: common questions

What microcontroller does the WLED PCB D1 Mini use?

The WLED PCB D1 Mini is built around the WeMos D1 mini, from the ESP8266 family.

How big is the WLED PCB D1 Mini?

The WLED PCB D1 Mini measures 49.5 × 35.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WLED PCB D1 Mini?

6 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the WLED PCB D1 Mini design files?

From the f2daz/WLED_PCB_D1_Mini repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the WLED PCB D1 Mini design in my own project?

Yes, under the terms of its MIT license, which f2daz chose for the repository.

Can I test firmware for the WLED PCB D1 Mini without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
