QFP-32 / LQFP-32 / FQFP-32 / TQFP-32 PCB Adapter Board with 0.8mm Pitch - SMD-to-DIP Converter for Breadboard-Compatible Prototyping
Fine-pitch QFP-32 packages with a 0.8mm pin pitch are among the most commonly used SMD IC formats in embedded development, yet they are fundamentally incompatible with standard breadboards and through-hole prototyping setups. This SMD-to-DIP adapter board by 7Semi bridges that gap by converting QFP-32, LQFP-32, FQFP-32, and TQFP-32 footprints to a 2.54mm pitch DIP layout, allowing engineers to test and evaluate ICs directly on a breadboard without requiring a custom PCB. The compact board measures 45 x 23 x 1.7mm and accommodates 32-pin packages with precision-routed traces for signal integrity.
Designed for use in STM32 development, PIC-based systems, ESP32 workflows, and general embedded prototyping, this adapter significantly shortens hardware iteration cycles. Each board features clearly labeled pins, a Pin-1 orientation marker, and clean trace routing that minimises noise and ensures reliable connections. Whether you are validating a microcontroller before production layout or building a low-volume IoT prototype, this reusable adapter eliminates the cost and lead time associated with fabricating a dedicated breakout PCB.
