Flash Memory: 32 KB (ATmega328) of which 0.Digital I/O Pins: 14 (of which 6 provide PWM output).Maximum supply voltage (not recommended): 20V Specifications Microcontroller: ATmega328 Operating Voltage: 5V Input Voltage (recommended) 7-12V Input Voltage (limits): 6-20V Digital I/O Pins: 14 (of.1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and 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 and the second one is a not connected pin, that is reserved for future purposes.It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. ATmega16U2 instead 8U2 as USB-to-Serial converter. The board is based on the ATmega328P with an ESP8266 Wi-Fi Module integrated (datasheet).The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.Īdditional features coming with the R3 version are: It has 14 digital input/output pins (of which 6 can be used as PWM.

It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. keyestudio Uno R3 is a microcontroller board based on the ATmega328 (datasheet), fully compatible with ARDUINO UNO REV3. 27.50 Popular and well-supported by the community Digital I/O and analog input pins Supports serial, PWM, and SPI communication Genuine Arduino board. The Arduino Uno SMD R3 is a microcontroller board based on the ATmega328 (datasheet).
