Arduino UNO R3 Opensource Controller Develop Board w/ 1PCS USB Cable
Specifications:
- Pins changes: add 2pcs I2C pins near AREF pins(SDA and SCL are the copy of Analog 4 and 5, rather than extra I2C interface)
- Two pins are added near RESET, one is IOREF to tell the onboard voltage, another one is for pins
- More stable RESET circuit
- ATmega 16U2 replace 8U2, which means 16K flash R3 can run code faster
