Experience Level: Intermediate
Industry: Technology
EDITED!
We decided to simplify the circuit using a ESP8266 instead Arduino + nRF24L01. So the design should be a ESP8266 ESP-12E + 110/220V power source + 2 relays + 1 dimmer + 2 I/O output headers to connect sensors.
Cost and size matters! Design this board as a shield that we could only connect ESP-12E maybe would be cheaper than use ESP8266 controler built-in, but we are also open for suggestions.
The idea is to use this board for home/office automation, we already develop the software for communication between the modules and the frontend to user, but we need to shrink the hardware to be functional.
Ideas for the visual style: The smaller the better!
Things to avoid: Cost!
