PCB layout and design for IOT project

Hello,

Thank you for your interest in my project.

I'm looking to develop a 220v wifi realy board for IOT, this module will be programmed to control light switches and make them controllable through the smartphone.

This module should be as small as possible (~50mm x 50mm), as it should fit inside the wall behind switches.

Looking for hardware engineer who can contribute to this project, advise and help creating this module small as possible, safe to use and reliable.

the board should have the following features:

- Based on esp8266

- Operated by direct input of 110V-240v.

- 2 10A relays with derived NO and NC contacts (110v-240v)

- 2 BUTTON inputs - here we connect the on / off switches

- 2 SENSOR inputs - we connect sensors (Temp, Humidity, etc.)

- 1 ADC measurement input (e.g. to connect light intensity sensor)

- 1 CFG button to enable the module into the configuration mode

- 1 indication led

- Headers for 3.3v, GND, TX, RX

- Enclosure case design (for 3D printing) - 50mm x 50mm x 25mm.
