Description:
The UNO R3 ATmega328P CH340 development board is a cost-effective, Arduino-compatible solution ideal for electronics enthusiasts, students, and prototypers. Designed around the ATmega328P microcontroller, this board delivers full UNO R3 functionality while using the CH340G USB-to-serial chip instead of the more expensive ATmega16U2. This makes it an excellent alternative to the original Arduino UNO without sacrificing performance or compatibility.
With full support for the Arduino IDE, this Arduino compatible UNO R3 with USB cable comes preloaded with the standard bootloader, allowing for quick plug-and-play programming via USB. The board features 14 digital I/O pins (6 with PWM), 6 analogue inputs, a 16 MHz quartz crystal, a USB connection, power jack, ICSP header, and reset button. Whether you’re just starting with Arduino or looking for a reliable, affordable development board, the UNO R3 ATmega328P CH340 development board is a versatile and essential tool for embedded system projects.
