The Pololu 5423 module provides reliable load control in RC systems with full galvanic isolation. The SPST solid-state relay supports up to 6 A at voltages up to 60 V and is suitable for applications requiring silent operation, durability, and precise control using RC signals. The version without soldered connectors offers flexibility for adaptation to individual projects.

The high-voltage converter module enables voltage conversion in the range of 12-30V with an output power of up to 360W and generates sparks up to 5 cm long. The device operates in the frequency range of 30Hz-50KHz and has compact dimensions of 75 x 70.6 x 14 mm.

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.
