Hello Sir,
its an easy task for me.
I have 4 years experience in PCB designing in EAGLE( single multilayer and flex)
we can make this with the help of atmega328, pm01 and 5V relay. in very small size 40x40x20mm box.
Almost all projects I made are Arduino and ESP12 based. following are some example
1. ESP12E wifi + relay board + humidity&temp sensor Smart module
2. ESP12S wifi + relay board home automation board.
3. ESP12E wifi + RC522 RFID + BUCk converter module.
4. atmega328au + hm11+ relays car actuator module.
5. atmega328au + nrf24l01 + relays smart switch module.
6. atmega328au + mpr121 capacitive touch smart remote.
7. amega328au + LCD display + hc06(later hm10) + amplifier + strain gauge water mapping module.
8. Arduino Uno clone.
I will provide you all necessary files ( gerber, smd-coordinate, BOM, Eagle(.brd& .sch).
please, see my portfolio for more sample of my work.
or initiate chat I will share some 3D simulation of my work.
you can contact me directly at WhatsApp 9479694124.
thanks.
