Leaf Labs - Maple

The Maple is a improved version of the Arduino Uno. The Maple maintains the same pin and mounting hole positions as the Arduino Uno.

Specifications Top

The Maple boasts a modern 32-bit ARM Cortex-M3 processor (STMicroelectronics' STM32F103RBT6, ARMv7-M architecture) clocked at 72 MHz. The Maple offers higher resolution ADCs, PWM output, more GPIO and just more features in general. The Maple retains the familiar Arduino form-factor and pin-outs, and can accept shields meant for Arduino boards.

The main difference between the Maple and Uno is that the Maple uses 3.3V for everything instead of the Arduino's 5V (though some of the I/O pins are 5V tolerant). LeafLabs also copied the Arduino's programming language and IDE; you can also program in C using the lower-level libmaple. If you are familiar with the Arduino, then you should have absolutely no trouble using a Maple.

The Maple boasts a modern 32-bit ARM Cortex-M3 processor (STMicroelectronics' STM32F103RBT6, ARMv7-M architecture) clocked at 72 MHz, and offers higher resolution ADCs and PWM output, more peripherals, more GPIO (than the Uno), more memory, and just more features in general
