This plastic bracket provides a convenient way to mount standard-size servos with a side flat to a surface. Rear view of Power HD Continuous Rotation Servo AR-3606HB and Solarbotics red servo wheel with Mounting Bracket for Standard-Size...

The A-Star 32U4 Mini SV is a programmable module based on the ATmega32U4 from Microchip (formerly Atmel). Unlike competing products, it has an on-board switching step-down regulator that allows it to be powered efficiently from a 5 V to...

This version of our STSPIN820 Stepper Motor Driver Compact Carrier ships with male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate 16-pin socket or solderless...

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...

Overview This current sensor is a carrier board or breakout board for Allegro’s ACS709LLFTR-35BB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS709 datasheet...

These tiny brushed DC gearmotors are intended for use at 6 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range (rotation can start...

This ball caster kit includes a black ABS housing, a 1/2" diameter plastic ball, two spacers (1/16" and 1/8" thick), and two #2 screw sets. The total height of the ball caster, 0.53", can be increased to about 0.7" using the included...
