설명

정품과 동일한 ATmega16U2 칩셋을 이용하는 Arduino UNO 보드입니다.

특별한 목적이 없다면 CH340 칩셋을 이용하는 저렴한 제품을 이용하는 것도 좋습니다.

 

UNO R3 development board ATmega16U2 ATmega328P single-chip microcomputer module with USB cable for Arduino

ATMEGA328P  UNO R3 
UNO R3 is an easy-to-use open source controller newly launched in 2012. Compared with UNO, there is no major change in hardware. The biggest difference lies in the USB-to-serial circuit part. Instead, it uses an ATMega16U2 microcontroller, so the cost is also somewhat different. Improve, the software part is the same as before, without major changes.
Features:
1. Pin changes: Two I2C pins are added next to the AREF pin (SDA and SCL are just copies of Analog 4 and 5, not an additional I2C interface), in addition, two pins are added next to RESET, one is IOREF , Can make the expansion board adapt to the onboard voltage, this pin only tells the current onboard voltage of the expansion board (for example, UNO is 5V, which can be regarded as a copy of the power pin, and does not provide level pull-up), and the other is for the future Placeholder pins to be used.
2. More stable RESET circuit. The position of the RESET button has also changed, and it has been moved to the corner of the board near the USB interface, making it easier to press.
3. ATmega16U2 replaces 8U2. This does not mean that R3 with 16K flash can make your code run faster. This update is for the USB interface chip. In theory, it allows UNO to simulate USB HID, such as MIDI/ Joystick/Keyboard.
Feature description
The circuit diagram of the original design is open, and the development software interface is free to download, or you can modify it yourself according to your needs. The downloading program is simple and convenient. You can simply use sensors and various electronic component connections (such as: LED lights, buzzers, buttons, photoresistors, etc.) to make a variety of interesting works.
Using a high-speed microprocessor controller (ATMEGA328), the development operation interface and environment are very simple and easy to understand, which is very suitable for beginners to learn.
Performance description
Digital I/O Digital input/output terminals are 0~13 in total.
Analog I/O Analog input/output terminals total 0~5.
Support ISP download function.
Input voltage: No external power supply is required when connected to the computer USB, and the external power supply is 7V~12V DC voltage input.
Output voltage: 5V DC voltage output and 3.3V DC voltage output.
Using Atmel Atmega328 microcontroller.

 

Note: The buckle of the injection molded case is relatively fragile, you need to press it before opening it, and you can’t open it violently! !
Product Details
1. The whole shell is composed of 6 pieces (3mm thick) transparent acrylic board, each piece is provided with different wiring openings and buckles.
2. The weight of the shell is relatively light. In order to save freight and transportation safety, it adopts detachable packaging with 6 pieces in a self-sealing PP bag.
3. The side plate wiring ports can be ventilated from left to right, and the cover plate has vents, which can be opened upwards, with good heat dissipation performance.
4. Each board has a double-sided protective film, which can be installed after tearing off.
