Teensy and related accessory purchase question

Development Boards Teensy

Hi! I wanted to do a project where I take input from a Bluetooth source, do FFT and have the microcontroller control some LEDs accordingly, then output the audio signal to speakers. It seems like a Teensy 4.0 is the right microcontroller for the job. I bought RN-52 breakouts from you all a while ago and would like to use those because they are what I have but am open to suggestions.

So, is a Teensy 4.0 and RN-52 enough to do the job? It looks like I need to do I2S from RN-52 to Teensy and I2S out to a converter and then on to a speaker? Or is there another kind of output that could go directly to the speaker/amplifier?

Thank you in advance for your advice!

Yep, although like you mentioned the Teensy outputs are digital so you’ll need either the Audio expansion board for Teensy or an external I2S DAC that would then go to a speaker :smiley:
