MKR2UNO Product Description
The MKR2UNO is a helpful shield if you want to easily turn your Arduino Uno Shields into a MKR based one. Just mount your Arduino MKR1000 onto the MKR2UNO adapter and then plug in any of your Uno shields. Please keep in mind that the MKR2UNO is just a form factor adapter and so does NOT present any voltage translation. Unlike the Arduino UNO, the MKR2UNO Adapter does NOT have I2C signals on A4 and A5 and SPI on pins 11, 12 and 13. Be careful before connecting a shield since shields without IOREF level shifting capability may not work properly.
