2014 UNO R3 Development Board Improved Version CH340G with USB
Cable
Product Introduction:
The Uno is a microcontroller board based on the ATmega328
(datasheet). 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.
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.
The Uno differs from all preceding boards in that it does not use
the FTDI USB-to-serial driver chip. Instead, it features the
Atmega16U2 (Atmega8U2 up to version R2) programmed as a
USB-to-serial converter.
The Uno can be powered via the USB connection or with an external
power supply. The power source is selected automatically.
External (non-USB) power can come either from an AC-to-DC adapter
(wall-wart) or battery. The adapter can be connected by plugging a
2.1mm center-positive plug into the board's power jack. Leads from
a battery can be inserted in the Gnd and Vin pin headers of the
POWER connector.
The board can operate on an external supply of 6 to 20 volts. If
supplied with less than 7V, however, the 5V pin may supply less
than five volts and the board may be unstable. If using more than
12V, the voltage regulator may overheat and damage the board. The
recommended range is 7 to 12 volts.
