2 PCS R3 Development Board, Single Board with ATmega328P Chip 2 KB 1 KB EEPROM, Microcontroller with USB Cable Compatible with Ar-duino uno
- ATmega 328P Chip: R3 board is equipped with an ATmega328P microcontroller with 14 digital I/O pins and 8 analog input pins, allowing users to connect a variety of sensors, displays, and other peripherals
- R3 Board: The ATmega328 has 32 KB (0.5 KB of which is occupied by the bootloader). It also has 2 KB and 1 KB of EEPROM (which can be read and written using the EEPROM library)
- Shield Function: Two new pins are also placed near the RESET pin. One is IOREF, which allows the shield to adapt to the voltage provided by the board, and the other is reserved for future use. The R3 works with all existing shields and can adapt to new shields that use these additional pins
- Atmega16U2 Chip: The R3 board can be powered through the USB connection or using an external power supply, the pin names are clearly printed on the header connector, making it more precise and easier to work with wires, the RX and TX LEDs on the board will flash when data is being transferred to the computer through the USB to Serial chip and the USB connection
- Ar-duino Kit: You don't need to worry about whether you can program it with Ar-duino IDE. You can use it just like an Ar-duino r3 board. R3 is fully compatible with Ard-uino UNO

R3 Development Board
Description:
Function:
Description:The R3 development board is a powerful microcontroller development platform based on the ATmega328P chip with 2 KB and 1 KB EEPROM, which is perfectly compatible with the Ar-duino-U-N-O.
It provides a rich input and output interface, including 14 digital pins and 6 analog input pins, suitable for a variety of embedded development and control applications.
The R3 development board is equipped with a USB port, which supports programming and power supply through a USB connection, facilitating rapid debugging and development.
Fully compatible with the Ar-duino IDE, you can directly use a wealth of open source libraries and sample codes to quickly implement hardware control, sensor acquisition, and other project functions.
Function:1.Pin change: Two I2C pins are added next to the AREF pin (SDA and SCL are just copies of Analog 4 and 5, with no additional I2C interfaces). In addition, two pins are added next to RESET. One is IOREF, which allows the expansion board to adapt to the onboard voltage. This pin only tells the expansion board what the current onboard voltage is (for example, is 5V, which can be seen as a copy of the power pin and does not provide level pull-up). The other is a placeholder pin for future use.
2.Stable RESET circuit: The RESET button's position has changed and moved to the corner of the board near the USB interface, which is more convenient for installation.
3.ATmega16U2: Enable R3 to simulate USB HID, such as MIDI/Joystick/Keyboard.
Parameters:
Input voltage (recommended): 7-12V
Digital I/O pins: 14 (6 of which provide PWM output)
Analog input pins: 6
DC current on 3.3V pin: 50 mA
Flash memory: 32 KB
Clock speed: 16MHz
