This adapter board breaks out a QFN-28 IC (with a body of 6mm x 6mm and 0.65mm 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).
