Arduino MKR2UNO Adaptor Shield
Adapt UNO shields for the Arduino MKR1000. Enables project upgrades with 3.3V operation, 14 digital I/O, and 6 analogue inputs.
The Arduino MKR2UNO Adaptor Shield offers a seamless transition from Arduino UNO to MKR-based platforms, enabling you to upgrade your projects with minimal effort. This clever adaptor transforms the familiar UNO form factor into a compatible interface for the more powerful MKR1000 development board, complete with its integrated battery charging capabilities.
One of the key advantages of this shield is that it allows you to continue using your existing collection of UNO-compatible shields with the advanced MKR1000. This protects your investment in hardware and simplifies the upgrade path for more demanding applications, from IoT prototypes to complex sensing projects. The adaptor maintains the standard pin layout, ensuring physical compatibility with a wide range of add-on boards.
It is important to note that the MKR2UNO is strictly a form factor adaptor and does not perform voltage level shifting. The MKR1000 operates at 3.3V, so shields designed for the UNO's 5V logic that lack their own IOREF level shifting may not function correctly without additional circuitry. Always verify the voltage compatibility of your shields before use.
