Micro Development Board Compatible with Arduino
Uno R3 is the clone one of the latest version of Uno with an on-board CH340 USB - serial converter chip. Even there are some little differences respect to original one, it is almost the same in terms of usage and software. This provides you a cheaper opportunitiy to get started with Arduino boards.
The microcontroller model of this board is the same as the original one (Atmega328). The only difference between microcontrollers is ther package.
This is the clone of one of Micro's latest verison. There is a usb connector cable in the content.
board is seperated from other boards by using ATmega32u4 microcontroller thus it does not need an USB - Serial converter. Through these features, can be introduced to computer as not only virtual COM port but also as peripherals such as console and mouse too.
Micro Development Board Compatible with Arduino Features:
can be supplied via usb or an external voltage source. External voltage source would be an AC - DC adapter or a battery. When it is supplied with an external adapter or battery, using 2.1 mm width, center-positive, 7-20 V power supply is recommended. Moreover, the connectors of the power socket on the board, Vin and GND pins are short circuited in backend. The battery can be connected to the board via GND and Vin pins.
It is not necessary to be connected to usb port during whole the operation. The board can be energized with only an adapter or a battery too, by this way, the board can work independently from the computer.
6 - 20 V can be used as an external supply but these are the limits for . Recommanded voltage supply for this board is between 7 - 20 V. Because the regulator on the board might not work stabile for the voltages below 7V. Likewise, it can be over - warmed for the voltages above 12 V.
Operating voltage of the s microcontroller is 5 V. The voltage supplies the board via Vin pin or the power socket on 7 to 12, V then this voltage is regulated and distributed to the board by the regulator.
Power pins are like that:
Atmega32u4 has an 32 kB flash memory (4 kB of this is used by the bootloader), 2.5 kB SRAM and 1 kB EEPROM.
Input / Output:
All of the 20 digital pins on the
can be configured as output or input pins. The logic level for all of these pins is 5 V. These pins work with 40 mA input or output current. Additionally, some of these pins have diffrent features too, listed below:
There are several options for . to communicate with another arduino or microcontroller. Atmega32u4 provides UART TTL (5V) Serial communication via its 0 (RX) and 1 (TX) pins. 32u4 connects to a computer by opening a virtual serial COM port and allows the serial communication. Arduino IDE, thanks to its serial monitor find in the computer software, provides to send and recieve text based information RX and TX leds on the board blink while the board is communicating via USB.
There is a phsycally serial port on the board but this number can be increased with theSoftwareSerial library as software.
Thanks to these features, can be introduced to computer as not only virtual COM port but also as peripherals such as console and mouse too.
board can be programmed with theArduino computer software (Arduino IDE). You can start programming by choosing under tools > board menu on the Arduino IDE. For details you may see thereferance and the basic functions page. Atmega32u4 on the Arduino board comes together with a specific software installed, named bootloader. Thanks to this it is not needed to use an external programming device to program Arduino . Communication is supplied by and original AVR109 protocol.
The board can be programmed by using ICSP headers via ISP programmer instead of bootloader software (Referance).
Usb high current protection:
board has restarable high current protectors. Even if your computer has its own protectors for its USB ports, the protectors on the board is adjusted to reject more than 500mA. If this amount of current is reached, protectors will keep open - circuit the connection untill the short - circuit disappears.
