The Mizar32 project makes it easy to use the hardware and software of a 32 bit microcontroller.

The hardware takes the shape of a 9x6cm main board with a 66MHz AVR32 UC3 processor and 32MB of RAM with additional stackable modules to extend its functionality.

By default it runs programs written in a modern high level scripting language, Lua or Lisp, with embedded extensions and is field-programmable: normally the user’s Lua or Lisp program is in a file on a micro SD card and the 128/256/512KB flash memory contains the interpreter that runs that program, but the flash can be reprogrammed with something else from a PC over USB.

Both the software and the hardware are aimed at newcomers to the embedded world who want an easy and powerful environment for rapid application development, for hardware prototyping, for quick production of a solution and for hobbyists to make their own custom devices.

The hardware is also offered to manufacturers to avoid a long design cycle and get a new product to market in a short time by simply adding any custom hardware on protoboards and writing a program to do what you want.


The hardware design is offered as an open standard and all the project files and manufacturing files are freely available to use, study and modify using open source software tools.
