You’ll need an amplifier between the speaker and the Bluetooth module. Something like this: https://www.amazon.com/dp/B077MKQJW2/ref=cm_sw_r_cp_api_glt_fabc_ASZFRXBBGRAW88J4P2GT?_encoding=UTF8&psc=1
But since that’s a 5 watt amp, you need a speaker rated for more than 5 watts. You’ll probably also want 2 speakers. The amp support two speakers and audio consists of a left and right channel (two outputs).
Do you want it to be rechargeable? You’ll also need a small BMS board to allow you to charge the battery.
Thanks, u/DrKrepz!
Here are some Amazon offering that state (ambiguously) that they operate on 5v. Which of these would work? Thanks in advance for helping me on this!
