Description
UNO SMD Board compatible with Arduino
The Uno SMD board is based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog 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 an AC-to-DC adapter or battery to get started.
The Uno SMD development board comes with a CH340G USB to UART converter chip. So in order to use this board, we need to install the CH340 driver. It can be powered via a USB connection or with an external power supply. The power source is selected automatically.
The AC-DC adapter can be connected by plugging a 2.1mm center-positive plug into the board’s power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
If you want to use this UNO SMD Board in your small or DIY projects, for that you will need few essential components like
