STK600 has two expansion connectors. All AVR device I/O ports, programming signals, and control signals are routed to the expansion connectors. The expansion connectors allow easy prototyping of applications with STK600.
The connectors to be used on an expansion board are manufactured by FCI and have P/N: 61082-101402LF. See also www.fciconnect.com for more information.
The connectors must be placed with exactly 119 mm from center to center. The expansion board must have a maximum width of 55 mm to avoid collision with components on the mainboard.
The pinout of the expansion connectors is shown in the table below.
