Re: USB cable


 

Bob,
Buy an ST-LINK adapter for a few bucks from this place where I got mine and you can read and write to the micro using the edge pins.
Works great.

I like the idea of soldering a cable to the board.? When my mind is sufficiently clear I will take a look and see if I can identify the appropriate places on the board.
I am not optimistic because the connector I removed had many pins, and I don't have a proper guide to where to make connections.? Further, when I tried at one point to apply 5V here or there I got no results.
What I have now works well and I am loath to repair it.? It's basically a cable coming from the nano and has a USB plug on the end.? The main things that could be improved would be to add the data lines and to have a socket on the nano.? The latter isn't going to happen.? So basically I just want to know where to connect the other two wires so I can transfer data.
It's not clear on the board, what goes where and I would be unhappy if I messed it up worse than it is.
If I need to transfer data I have the fully working unit I can use.? Most of the time I am content with local operation so it's not that important.? I get very accurate readings and don't want to monkey with the bit of success I have.

No problem.
We all get ahead when we 'play' with our 'toys'? ;-)

I'm glad that many people have noticed what the original author wrote in the "Know issues" section of the NanoVNA alpha1 kit assembly manual.
I think the same way, thank you for trying to confirm that I'm not trying in vain.

Good to know, Bob.?
I had suggested to the devs to use 2 LiPo s with a linear 5v Reg to run the
unit in order to reduce RFI from that charger/inverter chip.?
Banggood has a 2S charging board for about $2 that you run off of an 8 to 12v
source.? I'm going to look at that setup soon in addition to modding the
bridge and freq source circuits per the discussion on Hugen's GitHub repo.?
CheersLarry
