The XT60 to XT90 adapter allows for the integration of power sources and devices using different connector standards. This product is suitable for robotic projects, modeling, and test setups where flexibility in battery and power source selection is essential.

Pololu 2834

Step-up DC-DC converter module based on the LM2587 circuit, input voltage 3.5..30V, regulated output voltage 4..30V. The module is equipped with ARK connectors

Adapter 5.5 / 2.1mm - 5.5 / 2.5mm, straight, RoHS

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 6 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.
