Examples and Usages

LN_Digital

LN_Digital expansion board is designed to plug on to the 40 Pins LeMaker SBCs such as Banana Pro and LeMaker Guitar Base Board Rev.B, allowing you to sense and control the real world. With LN Digital you can detect the state of a switch, for example from a pressure pad, a door sensor or any number of other switch types. Once this state has been detected, you can write your own software for the Banana Pro that determines how to respond to that switch state. You can drive outputs to power motors, actuators, LEDs or anything else you can imagine!
