Arduino Compatible Smd Uno R3 Avrmega328p-Pu Development Board Controller With Usb Cable

Arduino Compatible SMD UNO R3 AVRmega328P-PU Development Board Controller With USB Cable Feature: Using ATmega16U2 instead 8U2 as USB-to-Serial converter, but does not mean its 16K Flash would make your R3 more faster, it is just serving for USB port Added SDA and SCL pins for TWI communication placed near to the AREF, but just the copy of PIN4 and PIN5 Two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board, the second one is a not connected pin which is reserved for future purposes Stronger RESET circuit, more stable, more convenience Specification: Arduino Compatible UNO R3 SMD Version Microcontroller: ATmega328 Operating Voltage: 5V Input Voltage (recommended): 7V ~ 12V Input Voltage (limits): 6V ~ 20V Digital I/O Pins: 14 (of which 6 provide PWM output) Analog Input Pins: 6 DC Current per I/O Pin: 40mA DC Current for 3.3V Pin: 50mA Flash Memory: 32KB (of which 0.5KB used by bootloader) SRAM: 2KB EEPROM: 1KB Clock Speed: 16MHz Package included: 1 x ATmega16U2 Arduino Compatible SMD UNO R3 1 x USB Cable
