The Maple is A 32-bit ARM development board. Coupled with the Maple IDE, the Maple line of development boards bring an Arduino style user experience to the world of powerful 32-bit ARM processors.
The Maple Mini is the breadboard friendly Maple development board featuring a smaller, 48-pin STM32 with the same speed and memory as the original Maple. Smaller than a stick of gum, the Maple Mini sports 120 KB Flash memory, 34 GPIOs and 20 KB of SRAM.
The Maple IDE will make Processing/Arduino programmers feel right at home. By swapping the popular "avr-gcc" compiler with CodeSourcery's "arm-none-eabi-gcc," LeafLabs manages to provide a nearly identical programming experience to Arduino despite targeting a completely different architecture.
If your current Arduino-based project is pushing against the performance limits of the ATmega, porting it over to Maple may be the fastest and easiest way to continue developing your project without starting from scratch. And with the form-factor of the Maple Mini, prototyping will be a breeze
