Open-source breakout board for 32–80 pin QFP SMD ICs with 0.8mm pitch (TQFP, LQFP, VQFP). Routes all pins to 0.1" header pads for breadboard or prototype wiring. Also available in 0.50mm and 0.65mm pitch.
Solderless options run from 830- and 400-point boards to 4.5×3.5 cm minis and self-adhesive translucent boards. Adafruit Perma-Proto PCBs copy breadboard rail layout onto solderable copper, so a working layout transfers directly. SMT adapters bridge QFN, TQFP and SSOP parts to 2.54 mm.
