Speaker (and amp?) suggestion w/ CLUE
Looking to add a speaker (and an amp?) to a CLUE. Is there a recommended accessory? Plan to play MP3 music, so stereo would be extra dope =)

Re: Speaker (and amp?) suggestion w/ CLUE
This stemma speaker would be the easiest to connect. It is recommended for the CPX and microbit.

If you want to get fancy and loud then consider the MAX9744 which is an i2c amp. The CLUE has a STEMMA QT port which you makes the i2c pin access easy. This buys you stereo @ 20W and you can use any compatible speakers.

@mikeysklar thanks for the reply.
A couple follow-ups on wiring and power. I'm updating one of those Tobbie-II robots.. finding space for extra boards and power is tricky as to not throw off the robot's balance.
Confirming-- the STEMMA port would not provide power for the MAX9744, correct? I'd need to add ext power source for it. Also, are there recommended wiring accessories to wire the board to the I2C 4-pin on the CLUE. This would def be the coolest if I can pull it all off =)
For https://www.adafruit.com/product/3885, I'd need a 4-pin STEMMA (CLUE board) to 3-pin (3885 board). Does Adafruit sell a pre-made cable for that?
Thanks

The MAX9744 would need a significant power source of 5-14v coming through it’s barrel jack or (12V -/+) pins. The i2c stemma connection would not be powering the amp.
The speaker stemma speaker 3-pin connection is GND / POWER / SIGNAL. It is not a i2c compatible device, but something you would manually wire into the CLUE.

https://learn.adafruit.com/adafruit-ste ... ep-3042084The easiest way to connect the STEMMA speaker to your project is the 3-pin JST connector at the base of the board. There are 3-pin JST to various connectors available, including to alligator clip and breadboard pin options, to make it super easy to connect it to any kind of project.
White Signal (SIG) This is 0-3V signal input, we decouple this signal so it can be AC or DC coupled.
Red Power (+) This is 3-5V DC power
Black Ground (-) Signal/power ground
