Solvline Eddy DK Ver 2.20 - Manual (Page 16)

Chapter 2. Getting Started
2.3.4.1. GPIO LED
GPIO ports provided by Eddy are maximum 16.
Not all Eddy modules provide GPIO port. Number of port can be limited or sometimes no port is provided at all due
to different characteristics of each module, such as using port for internal use.(Active High : 3.3V DC, Active Low :
0 V)
