The Pololu TB67S128FTG Stepper Motor Driver Carrier breakout board makes it easy to use Toshiba’s TB67S128FTG microstepping bipolar stepper motor driver, which features adjustable current limiting and microstepping down to 1/128-step. In addition, it has the ability to dynamically select an optimal decay mode by monitoring the actual motor current, and it can automatically reduce the driving current below the full amount when the motor is lightly loaded to minimize power consumption and heat generation.

The compact (0.4″ × 0.5″) D24V5F3 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 3.3 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 80% and 90% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 3.3 V. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9 V to 5.5 V and offers dimmable brightness control independent of the supply voltage. In general, the closer the object, the higher the contrast between light and dark readings, but high-reflectance objects are generally detectable out to around 40 mm. This version features the traditional-style QTR sensors without lenses.
