This example is a Baite clone of the Leaflabs Maple mini. This is an inexpensive ARM development platform with 128KB flash and 20KB RAM. This has double the flash capacity of the [[:boards:vcc-gnd|vcc-gnd]] which has the same controller. | This example is a Baite clone of the Leaflabs Maple mini.

The Maple mini board comes with a [[:tools:maple|USB boot loader]] along with the ROM based serial UART boot loader pre-installed. The USB boot loader is compatible with [[:tools:dfu-util|dfu-util]] and no programming hardware is necessary to begin development with the Maple mini. | The Maple mini board comes with a [[:tools:maple|USB boot loader]] in flash along with the ROM based serial UART boot loader.
