Well packaged, received in good condition and excellent delivery time (9 calendar days from order).
I find this "pin expander" very useful, especially for micro-controllers with limited I/Os. Most of the time I just need to read a snapshot of a sensor, rather than continuous monitoring, so it makes sense to cycle through a number of sensors, polling their current value, before taking and needed action and then going to sleep. This module fits that use case well and I am happy to recommend it.
Didn't come with headers, but nice
