BACK IN STOCK – Atmega32u4 Breakout Board. Toss out those FTDI cables and go USB-native with the ATmega32u4. After many months of back-orders, we finally received a shipment of these little guys and are excited to offer our breakout board. The little dev board 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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Can it still be programmed with the Arduino IDE, or do we need to use avrdude? If using avrdude, how do we write code for it? (Does it need to be in C?)
I still have problems with the driver on my Windows 7 (32 bit) system. The forum is a little overwhelming (7 pages and some comments lead to many more experiments). Is there a short version that is easier to understand. I had less problems with the Teensy or Sanguino, but I really want to use this board – it is much better than the standard Arduino…
hey lars, please feel free to post a new post in the forums and we will directly assist you. if you have a board that had the “beta” bootloader we’ll work with you and replace it in a jiffy.
I’m planning a project where size really matters and currently think about the layout of an atmel32u4 breakout board, which doesn’t only fit my purpose, but eventually get a more multiuse design.
So is there perhaps a atmel chip with the same computing power and pin numbre but smaller footprint.
Like the atmel328p, which has a smaller “brother” with smaller footprint (used e.g by the femtoduino project: http://www.varesano.net/projects/hardware/Femtoduino) ?
