Product description
100% compatible with UNO Rev3. Uses the same microcontroller, ATmega328. The only difference is that the board has been updated with a USB-C connector (the original uses a USB-B connector, which is now used less and less frequently).
What is the difference between UNO Rev3 and UNO Rev3 SMD?
The difference between the two versions is that the AVR chip (ATmega328) used in the UNO SMD is soldered directly onto the board, whereas in the original UNO the chip is mounted in an IC socket.
What is UNO?
UNO is one of the most popular and accessible microcontroller platforms in the world. Developed by Arduino.cc, it has become a favorite among hobbyists, educators, and professional developers. This is due to its ease of use, versatility, and extensive community support. UNO is a microcontroller-based development board equipped with the ATmega328P, an 8-bit microprocessor from Atmel (now part of Microchip Technology). The board is designed to be easy to use, even for those with no prior experience in electronics or programming. It features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a USB connection, a DC power jack, an ICSP header, and a reset button.
