A set of two magnetic encoders for use with Pololu DC Micro motors. The maximum resolution is 12 pulses per one revolution of the motor shaft. Powered from 2.7V to 18V. Pololu 4760

The compact (0.4″ × 0.5″) D24V5F1 synchronous buck voltage regulator takes input voltages between 3 V and 36 V and efficiently reduces them to 1.8 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 75% and 90%. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

Module with TMC2208 stepper motor driver. It enables control with a supply voltage ranging from 5.5 to 34 V and a current of up to 1,2 A

The USB Step-Up 9V 6W converter module converts the input voltage in the range of 4.2-5.2V to a constant output voltage of 9V, with a maximum current of 1A and a conversion efficiency of 96%. The device can operate in a wide temperature range, from -40°C to 85°C, which makes it ideal for powering various electronic devices in harsh environments.
