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!

The SparkFun Inventor’s Kit (SIK) is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete five overarching projects consisting of 16 interconnected circuits that teach everything from blinking an LED to reading sensors. The culminating project is your very own autonomous robot! No previous programming or electronics experience is required to use this kit. The full-color, spiral-bound SIK guidebook (included) contains step-by-step instructions with circuit diagrams and hookup tables for building each project and circuit with the included parts. Full example code is provided, new concepts and components are explained at point of use, and troubleshooting tips offer assistance if something goes wrong. The kit does not require any soldering and is recommended for beginners ages 10 and up. For SIK version 4.0 we took an entirely different approach to teaching embedded electronics. In previous versions of the SIK, each circuit focused on introducing a new piece of technology. With SIK v4.0, components are introduced in the context of the circuit you are building, and each circuit builds upon the last, leading up to a project that incorporates all of the components and concepts introduced throughout the guide. With new parts and a completely new strategy, even if you’ve used the SIK before, you’re in for a brand-new experience!

The SparkFun gamer:bit is a fun-filled “carrier” board for the micro:bit that, when combined with the micro:bit, provides you with a fully functional game system. Designed in a similar form factor to the classic Nintendo NES controller, the gamer:bit is equipped with a four-direction “D-pad” on the left side of the board and two action buttons on the right side of the board. The two push buttons on the micro:bit in the center function as start and select. The gamer:bit connects to the micro:bit via an edge connector in the center of the board, making setup easy. This creates a handy way to swap out micro:bits for programming, while still providing reliable connections to all of the different pins on the micro:bit. We have also included several poke home connectors on the back of the board that correspond to each button on the gamer:bit, allowing you to use external parts to control your game!

This simple 24AWG wire is terminated with a male JST connector at one end and a male JST-SM connector at the other. Each wire is a foot long and is capable of supporting a high voltage of 300VDC. These make for great connectors with WS2812 light projects! We use these cables almost exclusively on our Spectacle Light Board (DEV-14052) to hook up addressable LED strips (COM-12025), but that doesn’t mean you can’t find a different use for them! Dimensions: 1ft (0.3m) length.

The Spectacle Light Board allows you to add some fairly complex lighting effects to your Spectacle projects in a streamlined manner. Each has connections for you to add addressable LEDs as well as an external power connector. Designed to make it easy to add relatively complex lighting effects to your Spectacle projects, the Spectacle Light Board integrates with the rest of the Spectacle ecosystem to allow you to control lighting effects with ease and comfort. The Light Board is equipped with two 3.5mm TRRS jacks for Spectacle control signals from a Director Board (DEV-13912). The one labeled “In” should be plugged into a board that is closer to the Director Board than the Light Board is, or into the Director Board itself. Make sure to pay attention to the directionality of the jacks, as they will dictate how your Spectacle modules speak with one another and with the Director Board. As with every other Spectacle module, you will need the Director Board to operate any Spectacle project.

The Spectacle Audio Board allows you to add sound from a microSD card to your Spectacle projects. Each board accepts a microSD card with sounds in .ogg format, and has a 1/8" (3.5mm) audio jack line-level output ready to be amplified. It is important to know that the files used by the Spectacle Audio Board must be in OGG Vorbis format. This free codec has a higher compression ratio than MP3 and, more importantly, can be used without paying a licensing fee to any third-party organization. We use the free, open source program Audacity to convert from whatever the file’s current format is to OGG Vorbis. The Audio Board is equipped with three 3.5mm TRRS jacks: two for Spectacle control signals from a Director Board (DEV-13912) and one for an amplified speaker. The one labeled “In” should be plugged into a board that is closer to the Director Board than the Audio Board is, or into the Director Board itself. Make sure to pay attention to the directionality of the jacks, as they will dictate how your Spectacle modules speak with one another and with the Director Board. As with every other Spectacle module, you will need the Director Board to operate any Spectacle project.
