7Semi QFN28 Breakout Adapter PCB

The 7Semi QFN28 Breakout Adapter PCB is a small breakout board designed to make QFN-28 packaged ICs easy to work with on breadboards or prototype PCBs. It brings out all 28 pins to standard 0.1" (2.54 mm) spaced header pins or pads, simplifying development, testing, and integration of QFN28 chips.

Technical Specifications:

• Package supported: QFN-28 (28-pin QFN IC packages)
  
• Breakout format: All 28 pins routed to 0.1" (2.54 mm) standard header or pad layout
  
• Board type: Adapter / breakout PCB — no active components
  
• Suitable for manual soldering or reflow soldering for QFN-28 chip attachment
  
• Compatible with standard breadboards, perfboards, and custom PCBs using 2.54 mm pin spacing

Features:

• Converts QFN-28 package to standard 2.54 mm header footprint - ideal for prototyping.
  
• Enables use of QFN-28 ICs in breadboards, perfboards, or PCBs not designed for QFN footprints.
  
• Simplifies debugging, testing, and breakout of small-footprint ICs.
  
• Useful for development boards, prototypes, and custom circuits without dedicated QFN footprints.
  
• Supports both through-hole header pins or solder pads, depending on your use-case.
  
• Compact adapter design - adds minimal footprint overhead when used in a project.

Applications:

• Prototyping with QFN-28 ICs on breadboards or perfboards
  
• PCB design and breakout of small QFN chips without designing custom footprints
  
• Testing or evaluation of QFN ICs before committing to full PCB layout
  
• Breadboard development and proof-of-concept circuits using QFN chips
  
• Hobby and DIY electronics using QFN-packaged sensors or controllers
  
• Embedded system prototyping where small package IC needs to be broken out to standard pins
