The MKR2UNO Adapter allows you to turn your Arduino UNO form factor based project into a MKR based one without too much effort! You can so upgrade your project with a powerful board with integrated LiPo battery charger.
Operating Voltage 3.3V Input Voltage (recommended) 7-12V Input Voltage (limit) 6-16V Analog Input Pins 6 Analog Output Pins 1 Digital I/O Pins 14 DC Current for 3.3V Pin 700 mA DC Current for 5V Pin 700 mA Length 68.6 mm Width 53.4 mm Weight 24 g
MKR2UNO is open-source hardware! You can build your own board using the following files:
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 others Arduino boards this adapter allows to power your MKR board using a barrel jack with center positive polarity or the VIN pin on the headers.
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:
