ATmega328P-AU CH340G Chip UNO R3 Development Controller Board With
The Uno board Clone is a microcontroller board based on the
ATmega328. 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.
Open circuit diagram of the original design, the development of
software interface for free download, can also be in accordance
with the requirements and their modified, download the program is
simple and convenient. Can simply use sensors, all kinds of
electronic components connection (such as: LED lights, buzzer,
buttons, photoresistance, etc.), make all sorts of interesting
work.Microprocessor controller, using high-speed development
interface and the environment are very simple and easy to
understand, very suitable for beginners to learn.
|Input Voltage (recommended)||7-12V|
|Digital IO pins||14 (of which 6 provide PWM output)|
|Analog input pins||6|
|DC Current per I/O Pin||40 mA|
|USB Port||type B USB|
|Clock Speed||16 MHz|
|Input Voltage (limits)||6-20V|
|The largest output current||800 mA|
The power pins are as follows:
• VIN. The input voltage to the Arduino board when it's using an
external power source (as opposed to
5 volts from the USB connection or other regulated power source).
You can supply voltage through
this pin, or, if supplying voltage via the power jack, access it
through this pin.
• 5V. The regulated power supply used to power the microcontroller
and other components on the
board. This can come either from VIN via an on-board regulator, or
be supplied by USB or another
regulated 5V supply.
• 3V3. A 3.3 volt supply generated by the on-board regulator.
Maximum current draw is 50 mA.
• GND. Ground pins.
