LeafLabs Maple

The LeafLab Maple sports an ARM Cortex M3 chip 72MHz STM32 processor with 120KB Flash and 20KB SRAM.

The board is very compact but is compatible with Ardhuino shields form-factor.
The IDE or integrated development environment is called MapleIDE. It is compatible with the Wiring framework. As Processing-based Wiring-derived, it is platform-agnostic and runs on either Windows, Mac OS X or Linux. 

Unfortunately, many libraries are missing or still being developed.

Also, some widely used types have Maple-specific syntax, as uint16 instead of uint16_t.

Looking for more features, I designed a template I could use with Xcode:  embedXcode.

Pros

  • Powerful 32-bit ARM Cortex M3 MCU
  • Arduino shield form factor compatibility
  • Processing-based Wiring-derived IDE

Cons

  • Still many libraries missing 
  • Maple-specific syntax
  • Development seems halted

Wrap-Up

  • Compact board
  • Arduino shield compatibility
  • Software in development
