The Olimex is a fantastic board, however it provides no good way to mount it or connect sensors or other devices to it. This board provides a lot of flexibility. The Olimex board mounts neatly into 2 1x10 pin sockets. It then provides options for 2 1x10 pin headers, screw terminals. It also has the UEXT header mapped the same way as the Olimex board does. It has mount holes for generic mounting or for DIN rail clips (25mm spacing)
