The S9V11F5S6CMA switching step-up/step-down regulator efficiently produces a fixed 5 V (default) or 6 V (selectable) output whether it is higher or lower than the input voltage, which can range from 2 V to 16 V. (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that.)

The ACS72981 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 250 kHz) and low conduction resistance (0.2 mΩ), it minimizes energy loss and offers a fast response time of less than 2 µs. Pololu 5252
