The Uno R3 CH340G ATmega328P Development Board is an affordable alternative to the classic Uno R3 Arduino. It replaces the Atmega16U2 USB interface chip with the CH340G USB-to-Serial converter, maintaining most core functionalities of the original Uno. This board features an ISP header and supports programming via a standard USB B cable. Power options include USB connection or an external power supply through the barrel jack, with an onboard voltage regulator that accepts 7 to 15 VDC. It’s ideal for beginners and hobbyists looking for a reliable and cost-effective microcontroller platform.
