Hello all and welcome back to another Friday Product Post here at SparkFun Electronics! We have an audio-filled lineup for you this week, and we start it off with the new Wireless Speaker Kit! This kit combines several of our newest and most up-to-date audio boards with our new SparkFun IoT RedBoard (which utilizes the ESP32) to provide you with the means of creating your very own wireless speaker, no soldering required! We are also releasing a stand-alone version of the WM8960 Audio Codec Breakout with Headers, which you will find in the kit, as well! We wrap up the week with Arduino's new Opta Lite. Now, let's jump in and take a closer look at all of this week's new products.

SparkFun Qwiic Wireless Speaker Kit

The SparkFun Qwiic Wireless Speaker Kit provides you with everything you need to make a wireless audio speaker. In order to save you as much time as possible, we've soldered male header pins on the breakout boards! Wire the circuit up, upload code to the ESP32 RedBoard IoT Development Board, configure the Qwiic-enabled Audio Codec (WM8960), connect your audio BT source, and hit play to start jamming out to your favorite tunes!

The SparkFun WM8960 Audio Codec Breakout is a low-power, high-quality stereo codec with 1W Stereo Class D speaker drivers and headphone drivers. The WM8960 acts as a stereo audio ADC and DAC and communicates using I2S, a standard audio data protocol (not to be confused with I2C). This audio codec is chock full of features some of which include advanced on-chip digital signal processing for automatic level control (ALC) for the line or microphone input, programmable gain amplifier (PGA), pop and click suppression, and its ability to configure I2S settings and analog audio path through software via I2C. This version of the SparkFun Audio Codec Breakout includes pre-soldered male headers in order to get you up and running as fast as possible.

Arduino Opta Lite

Arduino Opta Lite


The Arduino Opta is a secure, easy-to-use micro PLC (Programmable Logic Controller) with Industrial IoT capabilities. Designed in partnership with Finder – leading industrial and building automation device manufacturer – Opta allows professionals to scale up automation projects while leveraging the Arduino ecosystem. Supporting both Arduino sketch and standard PLC languages, including LD (Ladder Logic Diagram) and FBD (Function Block Diagram), it was designed with PLC engineers in mind.

That's it for this week. As always, we can't wait to see what you make. Shoot us a tweet @sparkfun, or let us know on Instagram, Facebook or LinkedIn. Please be safe out there, be kind to one another! We'll be back with more new products next week so make sure to check back then. Happy hacking!

Never miss a new product!
