About this item

The Arduino Uno R3 CH340G Version Compatible Development Board is a low-cost alternative to the standard Arduino Uno R3, equipped with the ATmega328P microcontroller and the CH340G USB-to-serial converter instead of the Atmega16U2 chip. This board operates at 5V with a 16 MHz clock speed and provides 14 digital I/O pins (6 supporting PWM), 6 analog input pins, 32 KB flash memory (including 0.5 KB for the bootloader), 2 KB SRAM, and 1 KB EEPROM. It can be powered via USB or a DC jack (recommended 7-12V, limit 6-20V), is fully compatible with the Arduino IDE, and is ideal for DIY electronics, robotics, and educational projects
