Arduino UNO R3 With Case
Overview
This is the official Arduino UNO R3 with Chinese print labels onboard, of which pinouts and features are exactly the same as the original one:
- Compatible with former Arduino UNO shields
- ATmega16U2 is used as USB to UART converter, upgrade from ATmega8U2, faster and more stable
- Driver is integrated in Arduino IDE
- Brand new R3 only pins: SDA and SCL (next to AREF), IOREF and a reserved extension pin (next to RESET)
- Clear pin labels on the pinheaders, make it easier to use
What's Onboard
- Microcontroller: ATMEGA328P
- FLASH: 32KB (0.5 KB for bootloader)
- SRAM : 2KB
- EEPROM: 1KB
- Frequency: 16MHz
- Digital?I/O?pins: 14 (of which 6 can be used as PWM outputs)
- Analog input pins: 6
- Operating voltage: 5V
- I/O?current: 20mA(rec), 40mA(max)
- 3.3V pin current: 50mA
- Input Voltage (recommended): 7V-12V DC (not required when powered from USB)
- Input Voltage (limit): 6V-20V DC
