Fairy lights: common questions
What microcontroller does the Fairy lights use?
The Fairy lights is built around the WEMOS_D1_MINI, from the ESP8266 family.
How big is the Fairy lights PCB?
The Fairy lights measures 60 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Fairy lights?
6 components, from 6 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Fairy lights design files?
From the mylife-home/mylife-home-devices repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Fairy lights design in my own project?
Yes, under the terms of its GPL-3.0 license, which mylife-home chose for the repository.
Can I test firmware for the Fairy lights 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.
