8 mm × 13 101.0 × 16.5 analog 3.5 mA 31 mA 10 mm

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 and separate controls for the odd and even emitters. 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 high-performance, low-current QTRX sensors with lenses.

This powerful step-up/step-down regulator efficiently produces a fixed 24 V output from input voltages between 3 V and 30 V while allowing a typical output current of up to 2 A when the input voltage is close to the output voltage and offering typical efficiencies of 80% to 90%. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage.

The Tic T249 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a Toshiba TB67S249FTG driver with innovative and unique features that include Automatic Gain Control, and it ships with soldered header pins and terminal blocks. It can operate from 10 V to 47 V and can deliver up to approximately 1.8 A per phase without a heat sink or forced air flow (or 4.5 A max with sufficient additional cooling).

This breakout board for STMicro’s STSPIN220 low-voltage microstepping bipolar stepper motor driver offers microstepping down to 1/256-step and operates from 1.8 V to 10 V, allowing stepper motors to be powered with voltages that are too low for other drivers. It can deliver up to approximately 1.1 A per phase continuously without a heat sink or forced air flow (up to 1.3 A peak). The module has a pinout and interface that are very similar to that of our popular A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications.

This reflectance sensor module is designed specifically for use with the Balboa 32U4 balancing robot. It features five IR LED/phototransistor pairs that are great for identifying changes in reflectance on the ground directly underneath the Balboa (like detecting or following a black line on a white background). The sensor array offers dimmable brightness control, and each sensor provides an independent output that can be measured with a digital I/O.

This breakout board for Toshiba’s TB67S279FTG microstepping bipoloar stepper motor driver is arranged in the popular 16-pin Pololu form factor, making it a more compact alternative to our full breakout. It features adjustable current limiting and seven microstep resolutions (down to 1/32-step). Additionally, it dynamically selects 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 and heat. The TB67S279FTG has a wide operating voltage range of 10 V to 47 V, and our carrier board can deliver approximately 1.1 A per phase continuously without a heat sink or forced air flow (up to 2 A peak). It features built-in protection against under-voltage, over-current, and over-temperature conditions.

This shunt regulator can protect power supplies from voltage spikes generated by motor controllers they are connected to. This version has a fixed set point of 33.0 V, a shunt resistance of 4.10 ohms, and a total of 32 SMT shunt resistors populated on both sides of the PCB (this is the higher-power version). An external potentiometer can also be added to change the set voltage.
