7Semi QFN32 Adapter Board 0.5mm & 0.65mm – SMD to DIP Converter for STM ,AVR ,ESP Embedded Prototyping

Overview

Handling fine-pitch QFN32 ICs during prototyping is one of the biggest challenges in modern electronics development. The 7Semi QFN32 Adapter Board is designed to eliminate this barrier by converting compact QFN32 packages into a standard 2.54mm DIP format, making them fully compatible with breadboards and prototyping setups.

This adapter stands out by supporting two industry-standard pitches (0.5mm and 0.65mm) in a single board, allowing developers to work with a wider range of ICs without needing multiple adapters. Whether you're testing STM32 microcontrollers, ESP32 modules, or power and interface ICs, this board ensures reliable connections, precise alignment, and faster development cycles.

Its clean routing, clear pin labeling, and robust PCB design make it ideal for engineers, startups, students, and hobbyists who want to prototype efficiently without designing custom PCBs.

Features

• Supports QFN-32 IC packages with 0.5mm pitch (one side)

• Supports QFN-32 IC packages with 0.6mm pitch (other side)

• Converts SMD package to standard 2.54mm DIP format

• Breadboard compatible for easy prototyping

• Dual-side usability for wider IC compatibility

• Clear pin numbering and Pin 1 identification

• Strong solder pads for reliable connections

• Saves time by eliminating need for custom PCB

Caution

This adapter board features dual-side footprints to support pitch variants 0.5mm & 0.65mm . Please note that only one side can be used at a time. Using both sides simultaneously is not recommended, as it may lead to incorrect connections or short circuits. Always ensure that only the intended side is populated and connected during use.

Product include

QFN32 SMD to DIP Adapter Board 0.65mm & 0.5mm only, 2.54mm pin header/burg connectors not included
