@passive420 I sent you money some time ago for boards and I never received them. You also stopped replying to my DM's asking about them some weeks ago. What is going on? I'd like the boards or a refund please.

If this is of any help I have bought parts and pcbs from passive on 3 or 4 occasions and it was all fine.
I see that he was not seen here for quite some time...

I’m sure Richard will resurface. He’s a good guy.
We humans are like Teslas, needing to recharge from time to time.

Thanks for the feedback. I will be patient, then.

Yup, I've purchased a couple of things from him over the last 6 months and had no problems.
