I am a computer science teacher with students working on Raspberry pi 3 computers with 2x20 GPIO pins.
I am looking to purchase an addressable LED matrix to use in a classroom setting so students can draw text, shapes, etc. I would like students to be able to control the colour of each individual LED in their code and possibly use it to make a very simple game by moving the different lights around. What is the largest addressable LED matrix that you stock and which "HAT" would it need to make it work with a raspberry pi 3?
Thanks in advance for any advice you give me to get this project off the ground.

You'll most likely want a Matrix Hat https://www.adafruit.com/product/2345 and one of the 64x64 matrices from https://www.adafruit.com/category/327.

Re: Addressable LED matrix for classroom use
Thanks for the reply. :)
The website says the following about the 64x64 LED matrix:
"You can use these matrices with our RGB Matrix Bonnet for Raspberry Pi, RGB Matrix HAT (you'll need to connect a solder jumper), or Matrix Portal (ditto, jumper required). Other libraries such as our Arduino shield with Adafruit library, or our HDMI driver boards, don't support 5-address multiplexing! Check that your driver board is ok with 5-address displays first before purchasing."
Is the "driver board" the same thing as the RGB Matrix HAT?

Yes. The Matrix Hat is a LED matrix driver board.
