Hi all , I designed a circuit board interfaced with I2C BUS to Raspberry .
The board has the following features .
16 Relays
1 RTC ( clock )
1 EEPROM ( To save the configuration data , etc ... )
I2C BUS EXPANSION
Power Supply 24Vdc
I've done a little something in python to test the card , but I want someone more experienced to help me in making software that can also be operated by web .
In this way, the card could be used in various fields , home automation , lighting management, irrigation systems .
I can send all the documents of both schematic card gerber , materials list for the realization and also a champion who helps me .
The entire project was completed with Kicad , the card is in SMD and THT technology .
The project must remain OPEN - SOURCE .
I remain available for further clarification.
