Pololu TB67S128FTG Stepper Motor Driver Carrier
US$
21.02
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.

MAX14870 Single Brushed DC Motor Driver Carrier
US$
22.52
This compact breakout board for Maxim’s MAX14870 motor driver offers a wide operating voltage range of 4.5 V to 36 V and can deliver a continuous 1.7 A (2.5 A peak) to a single brushed DC motor. It features a simple two-pin speed/direction interface and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature.

3.3V, 500mA Step-Down Voltage Regulator D24V5F3
US$
6.93
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.

4107-POLOLU QTR-HD-07RC Reflectance Sensor Array: 7-Channel, 4mm Pitch, RC Output
US$
7.56
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.
