Say hello to Unduino1284p! This mini-sized Arduino-compatible MCU board is really compact but still very powerful, and most important of all, super easy to use. Sporting the ATmega1284p processor, it offers lots of IO pins, 16 kilobytes of RAM, 128 kilobytes of flash, high-precision ADCs, and much more. It is USB-powered, and connects directly to a host over USB for programming and serial communication. It measures less than 5×3 centimeters.
It’s truly a great board in a form factor that will fit into almost any project. It is also easy to place it in a breadboard for development. All pins of the ATmega1284p are broken out on the board.
I’m currently testing the latest revision of the design, and so far it is looking like everything is going to check out, which means that these should be available in my shop in a week or two. If you have any questions, post them in the comments!

  1. Hello, has this product been released? I could use a very small board like this as a protocol converter for a proprietary RS485 bus using 9-bit addressing and an oddball bit rate.

    1. Hi Andrew
      It hasn’t been released for the sole reason that I have not yet gotten around to writing a manual for it. I actually have quite a few of them produced already, and it is supported in the Arduino IDE as well. I use them often for my own prototyping and various projects. So if you can do without the manual, I can sell you some. You can write me an email, and we can figure out the details.
      Kind regards,
