About Arduino Uno R3 Compatible ATmega328P CH340 Development Board

The Arduino Uno R3 Compatible ATmega328P CH340 Development Board is a low-cost, Uno form-factor microcontroller board for electronics prototyping, STEM learning, automation and robotics. It uses the ATmega328P 8-bit AVR microcontroller running at 16 MHz and provides the standard Uno R3 pin layout, making it compatible with many Arduino shields, jumper wires, sensors and modules. The CH340 USB-to-serial chip allows programming and serial communication through a USB connection; some computers may require the CH340 driver. The board offers 14 digital I/O pins, 6 PWM-capable pins, 6 analog inputs, onboard 5 V regulation, USB power and external DC jack power support. It can be programmed from the Arduino IDE using the Arduino Uno board profile. This compatible board is suitable for LED projects, motor control, sensor interfacing, IoT experiments, classroom labs and quick embedded proof-of-concept work where an economical Uno R3 replacement is required.
