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...

This NEMA 23-size hybrid stepping motor can be used as a unipolar or bipolar stepper motor and has a 1.8° step angle (200 steps/revolution). Each phase draws 2 A at 4.5 V, allowing for a holding torque of 14 kg-cm (190 oz-in). Overview...

The GP2Y0A60SZ distance sensor from Sharp offers a wide detection range of 4″ to 60″ (10 cm to 150 cm) and a high update rate of 60 Hz. The distance is indicated by an analog voltage, so only a single analog input is required to...

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...

Overview These sensors are a great way to quickly detect the presence of nearby objects. It consists of a Sharp GP2Y0D805, GP2Y0D810, or GP2Y0D815 sensor module installed on our tiny carrier board for these sensors, which includes all of...

This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be...

Motor Connections These wheels are designed to press-fit securely onto the 3mm D output shafts on many of our gearmotors, including our micro metal gearmotors and our mini plastic gearmotors. They also work with our 35:1 and 115:1 15.5D...

This ball caster can be used as a replacement 3pi robot part or as a general-purpose ball caster. When mounted through a hole in a chassis that uses our micro metal gearmotors and our 32×7mm wheels , as on the 3pi, this ball caster is...
