Arduino UNO R3 ATMEGA328 Development Board
Description:
UNO R3 development board is 100 percent compatible with original Arduino DIY. And it has perfect quality and performance.
Main Features:
More pins: 2 more I2C pins are added by the side of AREF pin (SDA and SCL, copies of Analog 4 and 5, not extra I2C interfaces); Moreover, two other pins are also added by the side of RESET. One is IOREF, which enables
the expansion board to adapt to the on-board voltage. And the other is a stand-by occupied pin.
More stable RESET circuit: The RESET has been moved to the board corner, near to the USB interface, which is more convenient to use.
5V USB powered.
Built-in flash memory: 32K.
External power source: 7 - 12V, 9V recommended.
Clock frequency: 1MHz.
