Arduino Uno R3 SMD Compatible Development Board

Description:

The Uno R3 CH340G ATmega328p Development Board is a cost-effective alternative to the popular Uno R3 Arduino. This version uses the CH340 USB to Serial converter chip instead of the Atmega16U2 chip.

We have extensively used these budget-friendly Arduino boards with CH340 chips and have found them to perform flawlessly. The CH340 chip is utilized only during programming and for serial output through the USB port. In regular operation, this board functions identically to the more expensive version without the CH340 chip.

Main changes from the older version:

• Two rows of holes for the pins (Male and Female), so it can be connected with normal female jumpers.
• Additional 3 rows of holes for wiring.
• Changes to the DIP package of ATMEGA328P to flat package.
• CH340G replaces Atmega16U2.

How to Use:

• Download the IDE Arduino

• Download the USB chip driver

• Plug in the UNO development board; the driver will be installed automatically.
• Select UNO from the menu.
• Select the COM port.
• The best choice first: Arduino comes with routine procedures, burn into it.

Features:

• The Arduino Uno R3 is a microcontroller board based on the ATmega328.
• It has 14 digital input/output pins (6 can be used as PWM outputs).
• 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
• It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
• The Arduino Uno R3 differs from previous boards as it does not use the FTDI USB-to-serial driver chip.
• Instead, it features the Atmega16U2 (or Atmega8U2 up to version R2) programmed as a USB-to-serial converter.
• Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.
• Note: The Arduino Uno R3 reference design can use an Atmega8, 168, or 328. Current models use an ATmega328, but an Atmega8 is shown in the schematic for reference. The pin configuration is identical for all three processors.
