Product Description

ATmega328P chip: The R3 board is equipped with an ATmega328P microcontroller, which has 14 digital I/O pins and 8 analog input pins, allowing users to connect various sensors, displays, and other peripheral devices.

R3 board: ATmega328 has 32 KB (of which 0.5 KB is occupied by the bootloader). It also has 2 KB and 1 KB EEPROM (which can be read and written using the EEPROM library).

Shielding function: There are two new needles near the reset needle. One is IOREF, which allows the protective board to adapt to the voltage provided by the circuit board, and the other is reserved for future use. R3 is suitable for all existing protective covers and can adapt to new shielding using these additional pins.

Atmega16U2 chip: The R3 board can be connected via USB or powered by an external power source, and the pin names are clearly printed on the connector, making it more precise and easier to use wires. When data is transmitted to the computer through USB to the serial chip and USB connection, the RX and TX LEDs on the motherboard will flash.

Ar duino suite: You don't have to worry about whether you can use Ar duino IDE for programming. You can use it like the Ar duino r3 board. R3 is fully compatible with Ard uno UNO.
