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 Maple. Maple Mini also sports a complete silkscreen, making it uniquely detailed for a board its size.
Dimensions: 2.02 x 0.72 inches
Microprocessor: 32-bit ARM Cortex M3 at 72MHz (STM32F103CBT6)
Memory: 120 KB Flash and 20 KB SRAM
I/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 USARTs
Other:
Sleep, stop, and standby modes; serial wire debug and JTAG interfaces
