STD MSKZIO-Bus-PCA9665-I2C-Controller-V7-PUBLIC

Project source: Cloned from MSKZIO-Bus-I2C-Controller
Description
This a PCA9665 I2C controller board for the MSKZIO-bus.
In the schematic I use a DS1678+ RTC device, but actually I would encourage to use the DS1307 RTC device - its compatible and the clock is working, even when power is turned off
