The ATTINY104-XNANO from Microchip is a ATtiny104 Xplained Nano evaluation kit. It is a hardware platform to evaluate the ATtiny104 microcontroller. Supported by the Atmel Studio integrated development platform, the kit provides easy access to the features of the Atmel ATtiny104 and explains how to integrate the device in a custom design. The Xplained Nano MCU series evaluation kit includes an on-board mini embedded programmer and no external tools are necessary to program the ATtiny104 host MCU that drives the board. It features mEDBG (auto-ID for board identification in Atmel studio, one green board status LED, programming, virtual COM port (CDC)). The onboard programmer can be completely disconnected from the host MCU or it can be used to program any other MCU with the tiny programming interface (TPI).
