Have some USB logic analyzer, multimeter or oscilloscope and bumping up against the frustration of a shared earth ground? The Offspring (known for being electrical engineers) wisely sang "Ya gotta keep'em isolated!" Power and signal isolation improves common-mode voltage, enhances noise rejection, and permits two circuits to operate at different voltage levels. This handy little low-cost  USB Isolator is exactly what you...

Totaling 380 pieces, this M2.5 Screw Set  is a must-have for your workstation. You'll have enough screws, nuts, and hex standoffs to fuel your maker tendencies for days on end!

*Ka-thunk* Pin down that PCB with our  Toggle Clamp , a sturdy and reliable way to quickly press and release with precision! A pogo-pin bed is a great way to connect and test boards without any soldering, but you have to somehow get that PCB aligned right and evenly pressed down on each pogo. After much experimenting, we settled on this toggle clamp and we use it all the time in our testing processes. This beauty is strong enough...

Doesn't this fixture clamp look like a character in a Pixar movie?  If you just drew two little eyes on it then you could just imagine it hopping around on nifty, adorable little adventures that are heartwarming and...sorry, we got carried away. This fixture clamp is a great way to hold a printed circuit board in place while you're testing or programming.  It comes with two mounting screws so you can attach the...

The Pogo Pin Probe Clip is a great way to test and connect with pin-point accuracy without soldering! It's sort of like an alligator clip with a built in springy pogo pin - so you can connect to any PCB pad for 'scoping, analyzing or multimetering The clip is strong enough to grip onto a PCB, but has a soft grip so it won't mar or damage circuits. The 'tongue' is a round-tip pogo pin - a little spring-loaded contact...

Kelvin clips are used whenever you need to get a measurement right at the contact points of a circuit or component. Even though these are grippy clips, each side of the clip is electrically insulated. So you can use it to grab onto a part (as seen above) and perform measurements. These can also be used in circuit if needed. The clip is bare and comes with two jaw contacts that are screwed into each side of the plastic clip. No wires are...

Testing and debugging is a challenging step in board manufacturing. It can be super tricky on a fully populated PCB. So how can you test connections when you have an assortment of components blocking your probe? These Basic Micro SMT Test Hooker have solderable tabs on one end so you can attach a wire, and on the business end, a spring-actuated double-hook.They easily snap onto your project, and they're ideal for ultra-low profile...

Totaling 420 pieces , this M3 Screw Set  is a must-have for your workstation. You'll have enough screws, nuts, and hex standoffs to fuel your maker tendencies for days on end! M3 size screws fit a number of Adafruit breakout/dev board standoffs. Since they are nylon you can file them down easily, and they don't conduct electricity or interfere with antennas/magetometers. This set even comes in always-fashionable...

We're always digging around for various test lines to use with our power supply - whether we're checking current draw of our Feather, or trying out new LED samples. We picked up one of these and its so handy we use it all the time now. It's compact and has three of the most useful connectors on the end. Great for use with your bench top equipment or even a multimeter with banana jacks. Each connector has two banana plugs that go into...

Not to be confused with ODB, OBD stands for On Board Diagnostics and is used for analyzing and diagnosing vehicles. It's the thing your mechanic plugs into to find out why you've got a blinking engine light. Technically, OBD uses CAN bus and, hey, whaddya know, we've got some CAN-capable microcontroller boards here at Adafruit so this OBD Plug (16-pin) to DE-9 (DB-9) Socket Adapter Cable will come in super handy when you want to...

Quick connector wire sets make wiring up our arcade-style or metal buttons quicky-quick. Each wire comes as a 'pair' with two 0.187" quick-connects pre-crimped. The wires are terminated together in a JST 2.5mm 2-pin connector. This connector will fit in 0.1" headers, so it's breadboard compatible or you can stick two wires into the end. Of course, you can chop this off if there's no use for it. If you need a...

This board makes it easy for you to interface your Binho Nova host adapter with any Feather form-factor device. I2C, SPI, and UART interfaces are all wired up. By default, the 3V3 and 5V rails are connected so that the Binho Nova can power the sensors, but this can be easily disabled by cutting the exposed traces. Additionally, this interface board features a STEMMA QT / Qwiic connector to easily bridge the Feather and Qwiic...

This board breaks a male 2x5 1.27mm connector out to breadboard-friendly 2.54mm / 0.1" pitch headers. It's an easy way to interface your Binho Nova host adapter with other circuits using standard jumper wires as well. The board measures 14mm x 18mm x 7mm and is black with white silkscreen labels for each of the pins. The SMT connector comes soldered to the board, but you'll need to install the headers (included) yourself with a...
