Uno R3 CH340G ATmega328p Development Board

Uno R3 CH340G ATmega328p Development Board:

Uno R3 – connects to the computer via micro-USB cable (used for almost all Android smartphones).

You can supply power to board through the Micro USB connector or DC-jack.
The voltage regulator (LDO) can deal with incoming voltage from 6V to 12V DC.
Output current for 5V – about 800mA, for 3.3V – about 180mA (Please note that the higher the input voltage the lower the outgoing current).
That will provide a reliable power most of your initial projects. We recommended supply 7-9V.

We have used plenty of these low-cost Arduino boards with CH340 chips, and have found them to work perfectly. The only time the CH340 chip is used is during programming and when using the serial output of the USB port. During normal operation, this board is identical to the more expensive version without CH340 chip.

It has ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
The Uno R3 CH340G ATmega328p Development Board is the low-cost version of the popular Uno R3 Arduino.
It is assembled with the CH340 USB to Serial converter chip, instead of using an Atmega16U2 chip.
