All electronics ship with US style plugs.You may need a voltage converter or a plug adapter.
Special Features
Easily add 8 more I/O or A/D channels to your project through I2C. On board solder-jumpers allow selection of 16 different addresses, and optional 2200 ohm bus pull-up resistors
Many support videos and extensive documentation available online.
Each pin runs a state machine that can be assigned a specific function such as Servo, Rotary Encoder, A/D conversion, UART Bridge, PID control, PWM Generation, Kepad decoding, Frequency output, button debouncing, pulse timing and much more
Use up to 16 boards on the same I2C Bus
Open source hardware and software, certified by the Open Source Hardware Association
3.3V or 5V operation. 5V operation is possible while communicating on a 3.3V I2C bus, allowing mixed voltage circuits or analog inputs.
Preprogrammed I2C Bootloader allows in-circuit upgrades when new firmware is released
