This is a 3-foot-long white audio cable that has been terminated with two TRRS connectors at each end. TRRS connectors are the 3.5mm 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 (as in hands-free headsets) or to carry a video signal (as in some MP3/MP4 players). If you’re hacking on something that has a 4-conductor audio jack, being able to plug straight in will keep your build clean and simple.

The MyoWare Muscle Sensor is now designed to be wearable, allowing you to attach biomedical sensor pads (SEN-12969) directly to the board itself. However, there still may be cases where you want to mount the sensor pads away from the other hardware; this is where the MyoWare Cable Shield comes in. This shield provides a 3.5mm jack where you can attach a three-electrode sensor cable (CAB-12970), allowing you to test and use the MyoWare Muscle Sensor without actually attaching it to your person.

Are you looking to add a lot of color to your project? These massive 32x32 RGB LED panels are an awesome place to start. You can create animations, games, or all sorts of other fun displays with them. Yes, you read that right: a 32x32 LED matrix, that’s 1024 LEDs on a 7.5" x 7.5" board. On top of all that, thanks to an IDC connector and a seamless frame, these panels can be daisy chained together to form even bigger LED displays. These panels require a regulated 3.3-5V supply for power which needs to be able to source a good amount of current – up to 2A in the worst case. Included with each panel is a 0.15" pitch 4-pin polarized connector power cable which is terminated with both a female polarized connector, and a pair of spade terminals. Needless to say, if you are looking for a large, cheap, and easy to use RGB LED matrix you’ve come to the right place.

Fingerprint scanners are awesome! Why use a key when you have one right at the tip of your finger? Unfortunately, they’re often unreliable or difficult to implement. Well not anymore! This great GT-521F32 fingerprint module from ADH-Tech communicates over TTL Serial so you can easily embed it into your next project. The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an onboard optical sensor and 32-bit ARM Cortex M3 processor. This module is the economical version of the GT-521F52 and can store up to 200 different fingerprints. It is capable of 360° fingerprint recognition and download/upload templates using serial interface. Additionally, the GT-521Fxx series features a resolution of 450dpi, with a false acceptance rate of <0.001% and a false rejection rate of <0.1% while only needing <1.5 seconds to identify a unique fingerprint!

If you need to add user input without using a button, then a capacitive touch interface might be the answer. The AT42QT1011 SparkFun Capacitive Touch Breakout offers a single, momentary capacitive touch button with easy-to-use digital I/O pins. The AT42QT1011 is a dedicated, single-button capacitive sense chip. The chip handles monitoring a conductive area for touch. As long as a touch (e.g., from a finger) is detected, the AT42QT1011 keeps the output line high. Otherwise, the line is kept low. You just need to provide a power source (1.8V–5V) and ground for the AT42QT1011 to work. Additionally, a PAD pin is available if you would like to create your own external electrode.

The TB6612FNG Motor Driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes: CW, CCW, short-brake and stop. The two motor outputs (A and B) can be separately controlled, and the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode. Due to popular demand, this version of the SparkFun Motor Driver includes pre-soldered male headers for ease of use. With the headers already soldered on, you can jump right in to using this little board without any assembly!
