DIL/NetPC DNP/9565: 40-pin DIL Connector Pinout

The mechanical interface between the DIL/NetPC DNP/9265 and existing devices and equipment is a JEDEC 40-pin DIL connector with 2.54mm centers. This allows the direct integration to a standard 40-pin DIL socket. The 40 pins in total are used for 3.3 volt power supply (2 pins), Reset in and RCM (2 pins), two serial interfaces (10 pins), 10/100 Mbps Ethernet LAN interface (4 pins), general purpose I/O (20 pins), and the USB host interface (2 pins).
