The Arduino UNO R3 SMD is an open-source embedded development board based on the ATmega328 microcontroller in an SMD package. As Atmel shifts more of its production to surface mount ICs, the traditional DIP packaged ATmega chips are becoming increasingly rare. To meet the growing demand, we now offer the UNO R3 with an SMD ATmega328. This board retains the same functionality and layout as the original PTH version, although the SMD package requires hot-air for removal. This transition should not affect the majority of users who rely on the robust and versatile capabilities of the UNO R3 for their projects.
