Each Director Board features two 1/8" (3.5mm) jacks for Spectacle control signals. Plugging one TRRS cable into the headphone jack on your programming device and the other end into the “Program” jack on the Director Board will send commands into the reliable SAMD21 microcontroller at the board’s core. All you need to do then is plug another TRRS cable into the “Direct” jack on the Director Board and the other end of it into the “In” jack on another Spectacle board, and you are set! Make sure to pay attention to the directionality of the jacks, as they will dictate how your other Spectacle modules speak with the Director Board.
Power to your Spectacle project is supplied via a microUSB port at the top of the Director Board. We have written an in-depth User’s Guide to help direct you through each step of setting up any board in the Spectacle product line. You will be surprised by how easy and quick it is to make yourself into a Spectacle!
Spectacle is a product ecosystem centered around a simple idea: creative people shouldn’t have to learn new skills to use electronics in their projects. You’ve spent years developing the skills you use, and SparkFun wants to recognize that and help you expand your creations to include electronics without requiring you to spend years learning about electronics and programming.
