Interesting. #HongKongPolice tweeted out the electronics in their supposed bomb plot (spoiler: they found no explosives).

Questions:
1) Should the police be tweeting this if it's so dangerous?
2) Simple search reveals Clover Pro 5.5 is a common audio part https://twitter.com/hkpoliceforce/status/1252957680907333633

We are no electronics expert, so can only search the component with a name in the image. Maybe others can identify the other parts and say what they can be used for.
