2.54mm Pitch 20 Pin IDC Cable

This 48cm flat ribbon cable connects two 20 pin female IDC headers on a 2.54mm pitch. It is intended for developers and hobbyists who need a reliable link between debuggers, programmers or ISP download tools and target boards. The grey conduit construction weighs 25g and measures 2.5cm wide.

2.54mm Pitch Spacing

The single specification that determines compatibility is the 2.54mm pin pitch. Both ends are 20 pin female IDC connectors arranged in double rows, so the cable only fits headers built to that exact spacing. No other pitch or pin count will mate with this assembly.

Suits AVR JTAG and ISP Users

Builders working with Atmel AVR JTAG debuggers or in-system programmers will find this cable a direct fit. Buyers who need a different pin count, a male connector or a longer reach should look at other options.

Questions about this item

What does the 2.54 mm pitch mean when the cable is connected to a board?

The 2.54 mm pitch matches standard dual-row pin headers, so each connector aligns with 20 pins spaced at that interval.

How does the IDC connector interface limit the cable’s use?

The IDC sockets accept 20 pins in two rows; they cannot connect to single-row or differently spaced headers.

What clearance is needed to fit the 48 cm ribbon and its connectors?

The cable is 48 cm long and 2.5 cm wide, with 20-pin IDC ends that sit flush on standard dual-row headers.
