Adafruit LED Matrix Driver

I’m looking for a 128 LED matrix driver and came across the following by Adafruit:

• https://www.adafruit.com/product/1427
• https://www.adafruit.com/product/3090

Pimoroni only stock the latter, but as far as I tell these are identical, and seem to work from 3V to 5V depending on what LEDs you have attached. (I’m going to homebrew my own ‘matrix’).

Anyone know if that’s the case?

I notice the same chip is used in:

• https://shop.pimoroni.com/products/four-letter-phat
• https://shop.pimoroni.com/products/rainbow-hat-for-android-things

But I suspect Pimoroni have level shifted the I2C - which I’d probably end up doing for safety.

Cheers,
Tom
