Get started with AT32F407VGT7

Introduction

AT-START-F407 is designed to help you explore the high-performance features of the 32-bit

microcontroller, AT32F407 embedded with ARM Cortex

-M4F with FPU, and help develop your

applications.

AT-START-F407 is an evaluation board based on AT32F407VGT7 chip with LED indicators,

buttons, an USB micro-B connector, an Ethernet RJ45 connector, Arduino

Uno R3 extension

connector and an expanded 16 MB SPI Flash memory. This evaluation board embeds

debugging/programming tool AT-Link-EZ without the need of other development tools.
