AF-610

This power jack is designed to easily attach to a panel up to 8mm thick (0.315" or 5/16") and fit 2.1mm power plugs snugly and securely. Perfect for adding a power connector to your project enclosure. We like this jack in particular for its long body (so you can use it on thic...

SF-PRT-11476

This barrel jack plug is great for adding a common connector to the end of our wires. This jack is compatible with 5.5mm barrel jacks that have a 2.1mm center pole diameter. The outer shell unscrews to reveal solder terminals and a crimp strain relief. The outer shell has stra...

SF-PRT-09498

This is a right-angle, 24-pin Molex Mini-Fit Jr.™ connector, commonly used as the power supply connector on ATX motherboards. Two rows of twelve pins are broken out two rows of through-hole male headers. See the datasheet below for pin spacing dimensions.

AF-2788

This convenient 3.8mm/1.3mm or 3.5mm/1.1mm or 1.3mm DC to 2.1mm DC adapter cable lets you plug one of our solar panels into our optimized Solar Lithium Ion/Polymer charger!

SF-COM-10924

These are massive single pole - double throw (SPDT) sealed relays. This means that when current is applied to the coil it throws a simple changeover switch, terminating the connection from the NC contact to ground and closing the NO contact. Use them to switch high voltage/hig...

AF-373

This power jack is designed to fit 2.1mm power plugs snugly and securely. Perfect for adding a power connector to your project. We went for the more expensive "thin pin" type which snap into breadboards or perfboards. They will work where "thick pin" types go also, just need a...

AF-319

If you have a project where you'd like to be able to detach the wiring, this wire will fit the bill. Its a JST 2.5mm 'free hanging' cable assembly that latches strongly. One wire is marked with a white dashed line. You can't plug these in backwards.

SF-DEV-14150

The RELAYplate from Pi-Plates is the first dedicated relay board for the Raspberry Pi designed to meet the safety requirements of UL 60950 while being capable of switching 120 volts AC. Each of the seven relays is UL rated to switch 1 amp at 120volts AC or 30 volts DC. And, li...

AF-4029

This cable will let you turn a JST PH 4-pin cable port into 4 individual wires with grippy mini alligator clips. We're carrying these to match up with any of our boards or breakouts with 'STEMMA' connectors on them such as the HalloWing or NeoTrellis M4. Can also be used with ...

AF-4030

This cable will let you turn a JST PH 3-pin cable port into 3 individual wires with grippy mini alligator clips. We're carrying these to match up with any of our boards or breakouts with 3-pin 'STEMMA' connectors on them such as the HalloWing or NeoTrellis M4.

SF-SPX-15095

This is a 40-pin surface mount FPC (Flat Printed Circuit) connector. Nothing too fancy here, except that it can be plugged in either way - contacts up or down. This is useful for manufacturers because they only have to keep one item in stock. It is useful for consumers because...
