Arduino UNO R3 MEGA328P ATMEGA16U2 + USB Cable compatible
UNO R3 MEGA328P ATMEGA16U2 + USB Cable for Arduino development board - compatible
The Arduino Uno R3 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 crystal oscillator, 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 Atmega8U2 programmed as a USB-to-serial converter.
"Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduno, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the index of Arduino boards.
1.LED more ergonomic. Based the most advanced UNO32 solution, these four LEDs are moved to the most distal of the board convenient experimental observation.
2. more convenient analog input (output). All analog input a0-a5 gave on Vcc Gnd, so the plug can be used immediately (but please be careful polarity _ it's negative. Positive. Signals)
3. More convenient PWM output. We offer six groups PWM (or I / O) (but please be careful polarity _ its signal. Positive. Negative) terminal pin. Taking into account the stability, so we at the cost ofyour extra two regulators capacitance, so that will be more stable (master plus greater capacitance)
4. Increase the power and ground pins. We do not affect any of the functions under the premise, the more power pin (if you do not use, plus short-circuit sets to prevent contact with the top of theexpansion board short)
5. Increase the width of the copper platinum increased stability. Experience in customer master sharp-eyed will notice us this Arduino traces as wide as possible. Coarse alignment, when you used the instant fast output change,the waveform or beautiful. Again its structure will be a lot safer, because we found that some manufacturers of the Arduino copper platinum has been dropped offeasy, why they do this improved heart.
6. Max CCurrent Supercharged 3.3v. The power supply of the Arduino use of the FT232RL the 3.3V output, the maximum output current is only about 50mA, encounter requires a large current 3.3module, you will have enough power. Therefore, we use ASM1117-33 output 3.3V power supply, current 1000mA back your SD card to 3G_Sensor Zbee wii
