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.
