Arduino UNO SMD (CH340)

SKU: PE - 102 Category: Tag:


The?Arduino Uno SMD?is a version of the?Arduino Uno, but uses an?surface mount?version of the Atmega328P instead of the through-hole version. This version was made in response to a shortage in supply of the through-hole Atmega328P. The board is based on the ATmega328 (datasheet).

The Arduino Uno SMD is a rendition of the Arduino Uno, yet utilizes a surface mount variant of the Atmega328P rather than the through-opening adaptation. This form was made in light of a deficiency in stock of the through-opening Atmega328P. The board depends on the ATmega328 (datasheet). It has 14 computerized input/yield pins (of which 6 can be utilized as PWM yields), 6 simple data sources, a 16 MHz precious stone oscillator, a USB association, a force jack, an ICSP header, and a reset button. It contains all that expected to help the microcontroller; essentially interface it to a PC with a USB link or force it with an AC-to-DC connector or battery to begin.


The Uno contrasts from all former sheets in that it doesn’t utilize the FTDI USB-to-chronic driver chip. All things being equal, it includes the Atmega8U2 modified as a USB-to-chronic converter.


“Uno” signifies one in Italian and is named to check the forthcoming arrival of Arduino 1.0. The Uno and adaptation 1.0 will be the reference forms of Arduino, pushing ahead. The Uno is the most recent in a progression of USB Arduino sheets, and the reference model for the Arduino stage; for an examination with past renditions, see the record of Arduino sheets.
