Multi I/O Training Board for M1S

Multi I/O Training Board is designed to help one to add or extend various peripheral connections to GPIO pin header that used be done using jumper wires. Separating signals on GPIO header to multiple connections per different type of signals, this will help to easy wiring to peripheral devices and evaluate them. Also this board include several simple components that helps to test or use hardware functions.
