Velux: common questions
What microcontroller does the Velux use?
The Velux is built around the ESP-12F, from the ESP8266 family.
How big is the Velux PCB?
The Velux measures 67 × 62 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Velux?
25 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Velux 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 Velux 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 Velux 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.
