@kowshik1729 happy hacking and keep making.
all the best 😊 👍

@Abhay Glad that it helped you. Yes, I can suggest you with the queries as far as I know. All the best..!!✌

Hi @Mennyt , if you are looking for a cheap one then NK STAR USB 2.0 Mini Microphone will do the job well, or if you need better audio and special Audio processing algorithms includes VAD, DOA, Beamforming, NS, AEC and KWS you try the Seeed Studio ReSpeaker, also keep in mind normally USB Webcam has the built-in MIC and you can also utilize that too.

All the best with your project, Happy making.

@Gladiator54 There are some case raspberry fail to boot in my experience.

insufficient power from USB Adapter -> Try y to use 2/3 Amps Adapter

Broken Micro SD Card / OS FIle -> Try another uSD card

Polymeric Fuse failure -> It's self-resetting and usually return to normal operating parameters within a finite time, in such case check any shortage in the board PCB like small wires/coppers ..etc.

You can try load a new Raspbian OS with GUI and connect HDMI Monitor, if any error occurs you can see that, keep an eye on the ACT led (Green).

@kowshik1729
We couldn't find monitor during a hackathon and it cost the majority of our time to set up pi, this was the alternative that saved us back then.

Hope it will be helpful for you to @kowshik1729

This link has even more extensive ways to do it

@Suhailjr But I think since it's not a plug and plug play system and it will laying on the PCB for the long term, it might be fine. for me, it's similar to the Intel Edison and the PICO-IMX7 System-on-Module
