Polymorphic I2C Shield for Arduino MKR

I have a new product in my Tindie store - a multiport I2C shield for the Arduino MKR series.

Available with your choice of connectors and headers it supports

3V3 and 5V operation
top, bottom and stacking headers
0.1" and Grove connectors
top, bottom and sideways connectors
optional 2kB I2C EEPROM
up to 7 I2C connectors

As it is configurable in multiple ways to fit the needs of many IOT projects, I call it 'polymorphic'

Feedback and comments welcomed.
