This note details the pin mappings for the Smartmaker Smartcore microcontrollers to Arduino standards pins.
The Smartmaker1 Smartcores are small-form-factor Arduino clones.
The special thing about Smartcores is their use of the Smartmaker Open System I/O Smartbus, which is basically a snap-together bus interface for components based on pairs of the Hirose DF9-31 connector. There are two flavors of the bus, Smartbus Basic with two connector (A+B) and Smartbus Full which add two additional connectors (A+B+C+D). Each connector has 31 pins, which are assigned different purposes. The Smartmaker Wiki has more details on the Smartbus configuration.
