This adapter board breaks out a QFN-20 IC (with a body of 4mm x 4mm and 0.50mm pin pitch) into 0.1″ (2.54mm) spaced pins that match most breadboards and protoboards in the market.

This is a high quality PCB, with all the copper pads and contacts plated with Electroless Nickel Immersion Gold (ENIG) process, that offer an excellent surface planarity and oxidation resistance.

The land pattern includes a central pad that can be used to dissipate heat from high-power integrated circuits, like motor controllers and audio amplifiers. There is also a hole through the central pad that lets you drop some solder to ensure heat dissipation and conductivity up to the IC. This pad is connected to a dedicated outer pad, so you can wire a connection to GND (if needed).

By purchasing this item you will receive a pack of 2 QFN-20 adapter boards.


  • Standard thickness, high quality PCB.
  • Electroless nickel immersion gold (ENIG) contacts.
  • Fits any QFN-24 IC (body: 4mm x 4mm, pitch: 0.50mm)
  • 0.1″ (2.54mm) spaced pins.
  • Central pad for GND connection and/or heat dissipation.
  • Central pad hole and dedicated connection pad.

Salve, avrei bisogno di una breakout board per un package TQFN-20 5x5mm, per un chip MAX31865. Vorrei sapere se il footprint di questo articolo è compatibile con il chip che devo usare. Grazie.

Salve, questo prodotto e’ un 4x4mm, pin pitch 0.50, quindi non adatto per un TQFN-EP20 5x5mm pin pitch 0.65.
