If you're familiar with Arduino then you'll recognize the shape of the board, in fact the Maple is designed to be Arduino compatible and not just at the hardware level! 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.

Details

If you're familiar with Arduino then you'll recognize the shape of the board, in fact the Maple is designed to be Arduino compatible and not just at the hardware level! 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. Also, while some Arduino shields are incompatible due to certain capabilities being allocated to different pins, several of them are currently supported and there are more to come. There is also a guide available on the product page for porting Arduino libraries and source code over to Maple.

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.

Note: The silkscreen is incorrect for the power input range. The barrel jack can accept 5-12V and the VIN can accept 4-12V.
