ATmega16U2的Firmware（固件）也可以通过DFU工具升级，参见[[]]。
物理特征
Arduino UNO的最大尺寸为2.7 x 2.1 inches。
注意要点
Arduino UNO上USB口附近有一个可重置的保险丝，对电路起到保护作用。当电流超过500mA是会断开USB连接。
Arduino UNO提供了自动复位设计，可以通过主机复位。这样通过Arduino软件下在程序到UNO中软件可以自动复位，不需要在复位按钮。在印制板上丝印RESET EN处可以使能和禁止该功能。
扩展阅读
The UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family.
OVERVIEW
TECH SPECS
DOCUMENTATION
Arduino Unois 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 quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. 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.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
Uno means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.
