About this item

The UNO R3 CH340G ATmega328P Development Board is a cost-effective alternative to the official Arduino UNO, offering the same functionality with a few key differences. Instead of the original ATmega16U2 USB-to-serial converter, this board utilizes the CH340G chip, which is fully compatible with the Arduino IDE and supports the same programming and serial communication features. Powered by the ATmega328P microcontroller, the board operates at 5V with a 16 MHz clock speed. It features 14 digital I/O pins (6 of which provide PWM output), 6 analog inputs, and a micro USB interface for both power and data transfer. The board supports input voltages from 7V to 12V (with a maximum limit of 20V), making it versatile for various projects. Ideal for beginners and hobbyists, this development board is perfect for learning and experimenting with microcontroller-based projects. Its compact size and compatibility with a wide range of sensors and modules make it a popular choice for DIY electronics and prototyping. Included in the package is the UNO R3 CH340G ATmega328P Development Board with Micro USB and a set of male jumper headers.
