Simply mount your MKR1000 to this new adapter and plug in any of your UNO shields!

The MKR2UNO Adapter allows you to turn your Arduino UNO form factor based project into an MKR based one without too much effort! You can also upgrade your project with a powerful board with an integrated LiPo battery charger.


Please keep in mind that the MKR2UNO is just a form factor adapter and so is NOT present any voltage translation. Be careful before connecting a shield since shield without IOREF level shifting capability may not work properly.

Like in many other Arduino boards this adapter allows to power your MKR board using a barrel jack with centre positive polarity or the VIN pin on the headers.

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 does 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:
