Good, but not much information about it

DavidJanuary 2026

It works, but the website does not have much information on how to use it. Firstly, it is controlled via i2c but normally such chips have configurable addresses so that you can connect multiple to the same bus and have them on different addresses by soldering pads on the board. This one does have that (3 pads, so up to 8 different addresses), but there is no mention of that in the downloadable documentation or on the product page. Secondly, I got two and one of them is orange in colour whereas the other is red. There is no mention on the packaging what the colour is, and the page just says "in either red or yellow". It does not appear to use multi-colour LEDs so I assume that some are red whereas others are orange/yellow.

Yes, I recommend this product.

limited dimensions available

The display works great. Until you want to mount it. Cant find the hole dimensions anywhere so have to measure it
