Ready to scale your Arduino Uno design? Get the ATmega328P here!ĭigital I/O Pins: 14 (of which 6 provide PWM output)įlash Memory: 32 KB (ATmega328) of which 0. ![]() Performance between the boards are the same. ![]() The SMD version simply has the ATmega chip surface mounted on the Arduino board making it more difficult to replace. Click here if you're looking for the SMD version. Arduino R3 - Great little microcontroller. Arduino Part : A000066 Schematic Eagle Files Product Page Arduino IDE Download Tags. This version has the ATmega chip in a through-hole, so the chip can be easily replaced. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno. Its 32 kB Flash memory gives it enough room for most sketches/code to upload into the Arduino Uno. With a 16 MHz clock speed, it's able to perform instruction commands efficiently. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. ![]() The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. 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. 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. The Arduino Uno is a microcontroller board based on the ATmega328. Shop All Arduino Products HERE Arduino Uno Product Description
