: Many portable versions include probe lines (1.27mm, 2.0mm, or 2.54mm pitch) or spring thimble clips to read chips directly in-circuit without soldering. Common Sources & Documentation

However, field portability introduces challenges:

(often referred to as the K4 wires or welding line) to connect directly to circuit boards when a standard SOIC8 clip cannot be used.

The adapter bridges the gap between the main iProg programmer (often using a ) and the target chip. How to connect iProg+ Programmer to read chip

The adapter converts a (Small Outline IC) EEPROM (e.g., 24Cxx, 25Cxx, 93Cxx) to an 8-pin DIP (Dual In-line Package) for insertion into a standard programmer’s ZIF socket.
