7RelaysEtCommun: common questions
What microcontroller does the 7RelaysEtCommun use?
The 7RelaysEtCommun is built around the ESP-12F, from the ESP8266 family.
How big is the 7RelaysEtCommun PCB?
The 7RelaysEtCommun measures 67 × 93 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 7RelaysEtCommun?
42 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the 7RelaysEtCommun 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 7RelaysEtCommun 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 7RelaysEtCommun 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.
