This is a fantastically inexpensive method of getting input or output from an Arduino board. While other LCD and matrix displays have more flexible display output they usually require a larger number of connections. The ability to daisy chain additional units is a great bonus and it is commendable that they include the link cable with every unit. Build quality was good on the 3 units I purchased. There is a Arduino library with examples available to assist in getting these up and running. Board comes with brass spacer supports to sit on.
I purchased 2 units and then ordered another unit. The third unit I received was from a different manufacturer with slightly different size. The brass spacers are not long enough to use for mounting in a box or back panel.
Works as advertised.
Supported by Arduino Library.
Good build quality.
