Product Description

Toss out those FTDI cables and go USB-native with the ATmega32u4! Now available from Tronixlabs Australia is this neat little dev board that keeps it simple, with just the bare essentials:

  • Atmega32u4 - AVR core with USB capability. 32K flash, 2.5K RAM running at 16MHz
  • Standard AVR 6-pin ISP connector for direct programming (when you need the extra space)
  • Big Bootload/Reset button
  • 500mA fuse on the USB power line
  • Power LED and 'user' LED (also indicates when the bootloader is active)
  • Fits nicely in any breadboard
  • 4 mounting holes

This breakout board is best for those who have familiarity with some microcontrollers and are comfortable with writing code in C. This board doesn't come with any 'learn to program' tutorials! If this is your first time with a microcontroller, we suggest going with an Arduino which is easier. Then when you want to upgrade, check this out.

Plug it in, connect a mini-B USB cable and you can start writing code immediately. With the built-in bootloader you don't even need an AVR programmer. We suggest checking out the LUFA library to get started with the USB core as nearly every kind of device has an example already.
