External 0.1µF decoupling capacitor placed between VCC and GND. Step-by-Step Portable Wiring Instructions
When using an iProg EEPROM adapter board, the pins are typically labeled. If you are using a test clip (e.g., SOIC8 clip) connected directly to an adapter, follow this mapping: iProg Adapter Pin EEPROM Pin (SOIC8) Description VCC Power (3.3V/5V) SDA/MOSI Serial Data SCL/SCK Serial Clock CS/SS Chip Select (for SPI) WP Write Protect iprog eeprom adapter pinout portable
Most portable iProg adapters follow a standardized layout where signals are routed to specific pins on the ZIF socket. Below are the mappings for the most common adapters included in the kit. External 0
Do not connect Vpp (12V) to a standard EEPROM. You will destroy it instantly. Below are the mappings for the most common

The iProg+ programmer is a staple tool for automotive electronics technicians. It excels at odometer correction, airbag reset, and immobilizer key programming. To work with EEPROM chips—such as the 24C, 25C, 93C, and 95C series—you must understand the adapter pinouts. This is especially true when modifying your setup for portable, in-field, or on-bench use without desoldering. 1. Core Component Functions
Designed for "on-the-go" field use, the adapter features a compact and durable build:
