Maple Mini

Maple Mini is a breadboard-able PCB for applications where space is limited or simply if a breadboard is the preferred prototyping tool. Smaller than a stick of gum, Maple Mini features a smaller, 48-pin STM32 with the same speed and memory as the original Maple, but 34 GPIOs. It can be powered by USB or an external supply. Maple Mini also maintains a complete silkscreen, making it uniquely detailed for a board its size.Dimensions: 2.02 x 0.72 inchesMicroprocessor: 32-bit ARM Cortex M3 at 72MHz (STM32F103CBT6)Memory: 120 KB Flash and 20 KB SRAMI/O Pins: 34 (of which 12 provide PWM output at 16-bit resolution)ADCs: 9 (at 12-bit resolution)Peripherals: 4 timers, 2 I2Cs, 2 SPI ports, 3 USARTsOther: Sleep, stop, and standby modes; serial wire debug and JTAG interfacesPlease visit here for documentation
