Information on the Maple IDE : the leaflabs website

Can also run with the Arduino IDE (greater than 1.5) by downloading the support files from here, and see also the wiki here.

It is supported as a Leaflabs Maple Mini Rev2.

________________________________________________________________________

The board is simplified from Leaflabs Maple Mini. They are completely compatible at software and hardware because the compositions of every ports and the bootloader are identical, while the only changes are the power supply and PCB layout (This board is 2-layer). So you can completely see the data of Leaflabs Maple Mini from its Web site.

Maple IDE Installation: leaflabs.com/docs/maple-ide-install.html

The board's figure:

1 - The programming language is basically the same with Arduino, even the source code of some simple project can be in common use.

2 - The MCU of our board is STM32 (ARM Cortex-M3 ); its Clock is up to 72MHz (8Mhz crystal with multiplier); it is 32-bit MCU; it has 128K Flash memory and 20 KB SRAM.

Basically all MCU of Arduino board is AVR; its Clock up to 16MHz; it is 8-bit MCU; it has 32K Flash memory at most and a little SRAM. Besides, the number of Maple's ports is more than Arduino's (You can see it easily from the photos).

4 - Our board is cheap and has highly cost effective.
