TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for "Tip, Ring, Ring, Sleeve," which reflects the fact that, unlike a standard stereo connector, this actually has three conductors and a ground. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players). This breakout board makes it easy to add a TRRS jack to your prototype or project by...

This is a simple SPDT slide switch - great for use as an ON/OFF button, or just as a general control switch. The pins are spaced by 0.1", however they are incredibly thin making breadboard use not recommended. The switch is rated for 0.3A at 50VDC. This switch is just a bit smaller than our popular SPDT Mini Power Switch, but uses the same pin spacing. Being smaller takes up less PCB space (good!), but it does make it a bit harder to hit and flip easily. Documents: Dimensional Drawing ...

These panel-mounting rocker switches have built-in indicator lights to let you know when your switch is engaged. They mount into a 20.2mm diameter hole and are rated up to 16A @ 12v. These simple SPST on-off switches have three terminals, the two that you would normally see plus a ground tab for the blue LED lamp inside. Although these are rated for 12v, the LED works with as little as 5V. Features: Blue LED Indicator SPST on-off Rated up to 16A @ 12v 20.2mm Diameter Mounting Hole Videos ...

This simple on-off switch is rated for 20A at 12V but who cares about all that, it looks way awesome. These toggle switches come with those missile switch covers that make your project look like something out of a spy movie. They're also a great safety feature to ensure that you don't accidentally fire the missiles (or whatever it is your switch does). As if you needed any more convincing, they're also illuminated with a small LED in the end of the switch. These can be panel mounted into a...

This inline switch is great when you just want a simple on/off toggle switch that's already enclosed. Inside is a simple rocker switch with solder terminals with crimp strain relief. Attach some wires, solder them in place, and press-fit the enclosure together and you have a clean-looking switch. Features: SPST 6A, 250VAC Press-Fit Enclosure Clicky Sound Documents: Datasheet Product Video ...

This is the Magnetic Door Switch Set, a small reed switch assembly specifically designed to alert you when doors, drawers, or any other aperture opens. These types of switches are primarily used in home security systems. One half of the assembly set on a window or door frame and the other attached to the window or door itself. When the switch set is separated from each other the contact is broken and triggers an alarm. When each magnet piece comes within 20mm of each other they complete the...

These are the sturdy little stomp switches that you find on guitar effects pedals. They’re 3PDT (three-pole, double-throw) type switches. These switches allow you to modify your effects for true bypass and lets you wire a status indicator LED. This is useful for stage performers, as it leaves no question if the "box" is on or off. These are the same Stomp Switches found in our Proto Pedal Kit. Use these as replacements in some types of effects pedals or, better yet, build your own! Includes: 1...

Now, you can easily add an HID/controller to your project! The SparkFun Qwiic Joystick combines the convenience of the Qwiic connection system and an analog joystick that feels reminiscent of the thumbstick from a PlayStation 2 controller and for that reason it's become a favorite of ours. The only thing that could make it better is a "smart" version, so we made one! With the pre-installed firmware, the ATtiny85 is acts as an intermediary (microcontroller) for the analog and digital inputs...

This is a 16mm deluxe thumb joystick and is very similar to the 'analog' joysticks found inside PlayStation controllers. Directional movements are provided simply by two potentiometers - one for each axis. These 10k potentiometers will read the position changes for the joystick's full range of physical motion. This joystick also has a select button that is actuated when the joystick is pressed down. The mechanical parts found in this joystick are mostly metal and are considered far sturdier...

This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side. We often use this board to allow a microcontroller control servos or other motors that use a higher voltage than the...

This is a breakout board for the Texas Instruments TXB0104 module. The TXB0104 is a 4-bit bidirectional voltage-level translator with automatic direction sensing. This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation...

If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the...
