برد آردوینو R3 UNO پلاس CH340

Arduino UNO board is a processor board with ATmega328P microcontroller. This Arduino UNO board is similar to the Arduino UNO R3 board, and instead of the ATmega328P processor, ATmega328P-au is used, which unlike the Arduino UNO R3 board processor, is assembled on the board in SMD form and with a TQFP package, and for this reason, this Arduino board UNO is also known as UNO SMD. Facilities such as a power supply socket, having 14 digital input and output pins, LEDs representing the status of the board, a reset button, a 16 MHz clock, the possibility of feeding through a battery and adapter, and the presence of a 3.3 V regulator are among the advantages of the Arduino UNO board. But the main difference between this board and the Arduino UNO R3 board is the use of the CH340 converter for serial communication on the board, which is why this board is known as the Arduino UNO CH340 board.

The Arduino UNO board with the CH340 chip supports all software, shields and modules compatible with Arduino boards and requires the installation of the CH340 driver to start the board.

Warning: the maximum input voltage of non-original Arduino boards is 9 volts, if a voltage of 12 volts is applied (despite what is mentioned in the data sheet), the board will be damaged.
