Product Details

Arduino UNO Rev3 SMD — The Classic UNO with Surface-Mount ATmega328P

The Arduino UNO Rev3 SMD (SKU: A000073) is electronically identical to the classic Arduino UNO Rev3 (A000066) — same ATmega328P microcontroller @ 16MHz, same pinout, same full compatibility with shields, libraries, and the Arduino IDE. The single difference: the ATmega328P is Surface-Mount (SMD) rather than DIP, meaning it is permanently soldered to the PCB without a socket. This makes it a more compact choice for applications where chip replacement is not a requirement.

DIP vs SMD — What's the difference in practice?

On the classic UNO Rev3 (A000066), the ATmega328P sits in a DIP socket and can be removed and replaced. On the UNO Rev3 SMD, the same chip is permanently soldered (SMD) to the PCB — a more compact build, equally reliable, without chip replacement capability. For education and prototyping, both versions are functionally identical.

Who is it for?

Schools & educational institutions: Functionally identical to the UNO Rev3 — same sketches, same shields, same tutorials. Ideal for STEM and Computer Science labs where chip replacement is not a requirement.
Students: If you're already familiar with the Arduino IDE, the UNO Rev3 SMD programs and operates exactly like the classic UNO. No compromise on functionality.
Makers & engineers: The SMD version is preferred for embedding in custom enclosures and production projects where a compact build without a protruding DIP socket is an advantage. Combines with shields, sensors, and modules exactly like the DIP UNO.

Frequently Asked Questions

What is the difference between Arduino UNO Rev3 SMD (A000073) and Arduino UNO Rev3 (A000066)?
The two boards are electronically identical — same ATmega328P, same pinout, same functionality. The only difference is that the ATmega328P on the A000073 is SMD (permanently soldered), whereas on the A000066 it is DIP (removable). If you do not plan to replace the chip, the two versions are practically the same.

Can I use the same shields and libraries as the classic UNO Rev3?
Yes, absolutely. The UNO Rev3 SMD has the same pinout and full compatibility with all Arduino shields, libraries, and tutorials written for the UNO.

Why choose the SMD version over the DIP version?
If you don't need to replace the ATmega328P (e.g. after a fault), the SMD version is equally reliable and is preferred by engineers for applications where a compact build without a protruding DIP socket is an advantage.
