Arduino Nano Uno-compatible Expansion Shield
Convert your Arduino Nano or compatible board into an Uno with the Arduino Nano Uno-compatible Expansion Shield from PMD Way.
Simply insert your Nano with soldered pins into the fully-assembled shield, and you have full access to the I/O in the same manner as if the Nano was a Uno.
This allows you to connect Arduino Uno-compatible shields, plus PCB holes are provided to access all the I/O pins plus I2C, SPI and the UART connections.
Furthermore an Uno-stye power supply is provided with full polyfuse protection at 500 mA of current. Perfect!
