# Atmel AVR

> Atmel AVR support in Embedder for ATtiny, ATmega, AVR Dx and Ex families, and Adafruit AVR catalog boards, with programming and debug flows.

<Badge color="gray">Last Updated: 21 August 2026</Badge>

Select an Atmel catalog platform during project setup. The catalog covers ATtiny, ATmega, and AVR Dx/Ex devices, Curiosity Nano and Xplained kits, and Adafruit AVR boards such as Trinket, Gemma, and 32u4 Feathers.

<Note>
  This page lists every **Atmel** platform in the service catalog (60+ entries). The project setup picker is the source of truth for the catalog available to your team.
