The EPIC standard was developed by a combined effort from WinSystems, VersaLogic, Octagon Systems, Micro/sys, and Ampro.
Single board computers using this standard were available as early as 2004.
[2] EPIC modules are 6.5 × 4.5 inches (165 × 114 mm) in size, between PC/104-Plus and Embedded Board eXpandable (EBX) standards.
I/O connections can be either pin headers or PC-style connectors.
The standard provides specific I/O zones to implement functions such as Ethernet, serial ports, digital and analog I/O, video, wireless, and various application-specific interfaces.
