Uno R3 CH340G ATMega328P Development Board Compatible with Arduino

The Arduino UNO R3 SMD with the CH340G chip is a cost-effective version of the Arduino Uno R3. Here are its features and specifications:

  Features:  

• The low-cost version of Arduino Uno R3
• Uses CH340G USB to Serial converter chip
• Two rows of holes for pins (male and female) for easy connection with female jumpers
• Additional 3 rows of holes for wiring
• Changes the ATmega328P package from DIP to a flat package
• Identical to the more expensive version without the CH340 chip during normal operation

  Specifications:  

• Microcontroller Chip: ATmega328 (SMD) with CH340G interface
• Operating Voltage: 5V
• Input Voltage (Recommended): 7-12V
• Input Voltage (Limit): 6-20V
• Analog I/O Pins: 6
• Digital I/O Pins: 14 (6 provide PWM output)
• PWM Digital I/O Pins: 6
• DC Current for 3.3V Pin: 50mA
• DC Current per I/O Pin: 40mA
• Clock Speed: 16MHz
• SRAM: 2KB (ATmega328)
• EEPROM: 1KB (ATmega328)
• Flash Memory: 32KB (ATmega328) with 0.5KB used by bootloader
• Power Supply Option: DC Jack or USB
• On-Board LEDs: On/Off, L (PIN 13), TX, RX
• Operating Temperature: -40 to +90°C
• Dimensions (LxWxH): 75 x 54 x 12mm
• Weight: 26g

  Package Includes:  

• 1 x Uno R3 CH340G ATmega328p Board

This board is suitable for projects where cost is a consideration, providing similar functionality to the original Arduino Uno R3.
