These headers are made to work with the Teensy 3.2 and Teensy LC development boards. Each kit of headers makes your Teensy breadboard compatible and will allow for stacking a Teensy and Teensy-compatible shield board. This kit includes five headers (two 13-pin, one 7-pin, one 3-pin, and one 2x7 right-angle SMT), enough to connect your chosen Teensy in any configuration you need!

Because different parts sometimes use different voltage levels to communicate, voltage level translators can be the key to making different parts play nice. The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator that's operational on the low side from 1.2V to 3.3V and on the high side from 1.8V to 5.5V. Simply apply your low and high-side reference voltages to the VREF1 and VREF2 respectively, connect your I/O and drive the Enable pin high to open bidirectional voltage translation without the use of a direction pin!

The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presence detection.

So much power and light from such a small package. This 5 pack of "Cool" white 3 Watt aluminum backed PCBs is sure to shed a lot of light on any project you add it to. These LEDs act as any other LED except these little guys require much more power while delivering a light as intense of a thousand suns going super nova (this is an exaggeration but you know what we mean)! Each LED in the pack sits upon an aluminum backed PCB to help with heat dissipation and emits a cool white light. Additionally, each LED requires a forward voltage of 3.2-3.8V at 750mA.

This is an easy-to-assemble pan/tilt bracket kit that utilizes servos to move on two axes fit for camera and helping-hand applications. This particular bracket kit is the same one we use in our SparkFun Raspberry Pi Zero W Camera Kit to create a remote camera system for your home or workplace. Everything is included to get this kit assembled, even the servos (just be sure the servo motors are centered during assembly). All you will need is a small screwdriver set and a pair of clippers.

So much power and light from such a small package. This 3W per channel, Triple Output High Power RGB LED is sure to shed a lot of light on any project you add it to. This LED acts as any other LED except they require much more power while delivering a light as intense of a thousand suns going super nova (this is an exaggeration but you know what we mean)! Please be aware that with all three LEDs (9W total output), you will need additional heat sinking.

The Molex GNSS Flex antenna is a great option for basic GNSS applications and will work with any of our GNSS boards equipped with a U.FL at a fraction of the cost of many of its big brothers. This antenna supports GPS, Galileo, BeiDou, and GLONASS in three different frequency bands (1561 +/-3MHz, 1575 +/-3MHz, 1602 +/-3MHz).

The SparkFun GNSS Chip Antenna Evaluation Board makes it easy to test out various sized GPS antennas and geometries. Six different chip antennas have been populated on this board, each with a U.FL connector to attach your chip to the antenna! We've even v-scored the board so you can snap the six antenna's apart and just have the one you need. If you aren't picky about your antenna and/or each of the antennas work well for your applications, you will get six antennas to use in various project. Since these are GNSS antennas, they will work with GPS as well as GLONASS, Galileo, BeiDou, and other worldwide systems.

The SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The SparkFun SAM-M8Q GPS Breakout is a high quality, GPS board with equally impressive configuration options. The SAM-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery, you'll have backup power enabling the GPS to get a hot lock within seconds!

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.

This is a 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.

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!
