Fit a 3.3-volt buck regulator into a compact project with this BabyBuck breakout. It uses the AP63203 synchronous converter and plated through holes for input and output power. The small board trades the larger version’s connector options for reduced space, providing a soldered power-regulation component for a custom assembly.
