About this component
This Arduino Uno R3 CH340G is a budget-friendly development board based on the ATmega328P microcontroller. It uses the CH340G USB-to-serial converter chip instead of the standard communication chip.
It is fully compatible with the Arduino IDE and serves as an excellent option for prototyping robotics, home automation, and custom hardware projects.
The SMD version is particularly durable for vibration-prone applications like RC cars and automated rovers.
