UNO R3 ATmega328P Arduino Compatible CH340 Mini USB Board
The Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz crystal oscillator, 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 a AC-to-DC adapter or battery to get started.
This board uses SMD hardware which reduces the cost but has the same functionality. With more board real-estate there is a new header section for key IOs such as UART I2C and Power.
Main Changes from the older version:
- Add two rows of the holes for the pins. So it can be connected with normal Dubond line.
- Add 3 rows of holes for key IOs such as UART I2C and Power.
- Change the in-line package of ATMEGA328P to flat package.
- CH340G Replace ATmega16U2
