- SMD / SMT package: LGA-14 3.0 X 5.0 mm 0.80 mm pitch. - Adapter pcb board for breadboard prototyping. - PCB has a solder mask layer to minimise the formation of solder bridges during soldering. - For connectors with 0.1 inch pitch, not included. - A ground plane under the chip is available, with one pad connection. Properly connected can minimize noise in some circuits.
