Maple seems like an excellent alternative
I bought an Olimex Maple and it is no Arduino.
Please don't call it what it isn't.
The Olimexino-STM32 is not the "Olimex Maple." It is an Arduino and Maple-like board.
LeafLabs, the original makers of the Maple, licensed their software and hardware as open source. Anyone is able to build upon it and Olimex has.
