This is an inexpensive STM32F103CBT6 ARM Cortex-M3 development platform with 128KB flash and 20KB RAM. This has double the flash capacity of the [[:boards:vcc-gnd|vcc-gnd]] which has a similar controller.
  
-The Maple mini board comes with a [[:tools:maple|USB boot loader]] along with the ROM based serial UART boot loader pre-installed.
