A compact voltage converter module that reduces input voltage from 12.5 to 65 V to a stable 12 V at currents up to 700 mA. It features high efficiency, low quiescent current (<0.2 mA), and short-circuit and thermal protection, ensuring safe and efficient operation. Its small size and ease of integration make it ideal for mobile devices, battery-powered designs, and systems requiring stable power. Pololu 5437

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±30 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 44 mV/A and a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5441
