A no-frills two-pack of the classic LM2596 step-down module. No display — you set the output with a multimeter and the trim pot — but they do the essential job: take a higher-voltage source and hand your servos a stable 5–6V. A dependable, low-cost choice when you already know your target voltage and just need clean regulation between the battery and the servo rail.
