Quantity:

This version of the FS90 micro servo from FEETECH is specially modified to provide access to the feedback potentiometer through a fourth (green) wire, allowing you to directly measure the position of the output. This extra information enables more complex robotics applications, such as determining when the servo has reached its target, detecting when the output is blocked, or implementing your own higher-level closed-loop position control.

Key specs at 6 V: 0.10 sec/60°, 21 oz-in (1.5 kg-cm), 13 g.

This breakout board for STMicro’s STSPIN820 microstepping bipolar stepper motor driver offers microstepping down to 1/256-step and a wide operating range of 7 V to 45 V. It can deliver up to approximately 0.9 A per phase continuously without a heat sink or forced air flow (up to 1.5 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 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 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 high-performance, low-current QTRX sensors with lenses.

This Romi Chassis accessory offers a convenient way to expand your Romi robot vertically by adding new tiers. The expansion plate has the same diameter as the base plate, but we made it only a half circle to give you more expansion options. For example, when used as part of the Romi robot arm kit, it supports the arm in the back while leaving the front half of the Romi open. For a full-sized expansion platform, just combine two expansion plates. A mixture of mounting holes and slots give you the flexibility to mount components in a variety of orientations almost anywhere on the plate.

This expansion plate for the Romi chassis is made from black ABS.

This carrier for ST’s LPS25HB digital barometer measures pressures from 260 mbar to 1260 mbar (26 kPa to 126 kPa) with absolute accuracy down to ±0.2 mbar (0.02 kPa) and typical RMS noise of 0.01 mbar (1 Pa) in high-resolution mode. These pressures can easily be converted to altitudes. The board has a 3.3 V linear regulator and integrated level shifters that allow it to work over an input voltage range of 2.5 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards. The sensor offers I²C and SPI interfaces.

This product is a drop-in replacement for the original LPS25H pressure sensor carrier.

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 high-performance, low-current QTRX sensors with lenses.
