Datasheet

If you want to use the Arduino MKRZero and the Arduino WIFi shield 101 read the Arduino WIFi shield 101
reference to change module pins.
Unlike the Arduino UNO, the MKR2UNO Adapter do NOT have I2C signals on A4 and A5 and SPI on pins
11, 12 and 13.
All the pins on the MKR2UNO Adapter are wired one to one from the MKR to the UNO form factor with
some exception:
MKR form factor pin UNO form factor pin
0 13
1 10
13 0
14 1
