LedDimmer ESP8266: common questions

What microcontroller does the LedDimmer ESP8266 use?

The LedDimmer ESP8266 is built around the ESP-12E, from the ESP8266 family.

How big is the LedDimmer ESP8266 PCB?

The LedDimmer ESP8266 measures 50 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LedDimmer ESP8266?

19 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the LedDimmer ESP8266 design files?

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

Can I use the LedDimmer ESP8266 design in my own project?

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

Can I test firmware for the LedDimmer ESP8266 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.
