These hexagonal male-female aluminum standoffs are intended specifically for use with the Raspberry Pi. They keep parts spaced 18.6 mm apart, which is just the right height for mounting expansion boards with extra-tall female headers,...

These hexagonal male-female aluminum standoffs are intended specifically for use with the Raspberry Pi. They keep parts spaced 11 mm apart, which is just the right height for mounting expansion boards with standard-size female headers,...

These small, two-pin, SPST momentary pushbuttons are intended for mounting to PCBs, but they can also be plugged into standard 0.1" breadboards as shown in the picture to the right. We use them as reset buttons and user pushbuttons in...

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 is a bulk-packaged version of our Black Edition A4988 Stepper Motor Driver Carrier that ships with 0.1″-pitch male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate...

This product is a power switch implemented as a pair of P-channel MOSFETs configured as a high-side switch with reverse voltage protection and controlled by a micro slide switch. Because the main current does not go through the...

This 12 V light-duty (LD) linear actuator with a 5:1 gear reduction can lift loads up to 15 kgf [34 lbs or 150 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 43.9 mm/s [1.73″/s] at no load...

This 12 V light-duty (LD) linear actuator with a 20:1 gear reduction can lift loads up to 50 kgf [110 lbs or 500 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 14.6 mm/s [0.57″/s] at no...

90×10mm wheel with tire removed. Description 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 plastic gearmotors with 3mm D-shafts. They...
