I would like to use both a) mezzanine board and b) secure96 boards with Hikey 960. I assume I need some kind of stack header, otherwise many grove connectors are hidden by the secure96 board. I saw one proposed on https://github.com/96boards/96boards-sensors/commit/73021ebd3f4c55f3c6352203df1d511f63c52b79, but it’s not possible to trace where this can be bought from, and maybe it’s not for this purpose also?
Your help is appreciated. Also, please advise which library you propose to use for secure96? There are several ones that we have tried and do not work, but I assume there is one that works?
