Great work! Thanks.

So far no progress. I will compare each part of the circuit and components with the REBBEET module. I am suspicious of the quality of the QCAs purchased from Aliexpress. Has anyone had a similar problem?

I don't think it's related to the flash image. I got the .bin from: viewtopic.php?p=33730#p33730

Wow, I hope I don't have the same soldering problem on the 5 boards! That would be quite frustrating, I always check the soldering on the side pads with a microscope and they seem ok.

Thanks, uhi22. I'm using the board with the FLASH memory firmware as EVSE. I checked and the C10 is at an adequate ...

Thanks. I'll check these points.

Anyway, I'm more suspicious of a systematic error, since I have 5 cards and they all behave the same way.

Guys. I'm having trouble getting my QCA7000 board to work, so I'm looking for documents and projects that might give me some clues about what to do. I found a git file with files that might help everybody with the QCA7000 design. Here's the link: https://gitcode.com/open-source-toolkit/3c2616 and ...

Thanks, that's something good to hear!
I'll double-check the soldering, especially the center pad and ground pins — fingers crossed that's all it is!
Appreciate you sharing this!

Hi everyone,

I'm working with the QCA7005 and noticed an unusual waveform on its oscillator. Has anyone encountered this kind of behavior?

Also, I observed that the internal 1.2 V regulator is not regulating properly — it's rising to around 1.6 V.
I'm not sure if this is causing the oscillator ...

Hi Guys.

I'm using the QCA7000 board V4 on the EVSE side. My practical tests are with a TPlink AR7420 using pyPLC as PEV and sometimes with a BMW i3 2014.

In the QCA7000 board I have removed L5 and L7 that was grounding the RX signal.

In my tests with AR7420 the communication works 100% of ...

I made new tests and got new info:

1. I use 5V and sometimes 12V to power the AR4720 from a TPlink adaptor. I think it is hot all the time and maybe this wasn't the problem.

2. This original.pib was downloaded from the modem after some tests with it as EVSE (I must change its name when reading ...

Hi guys.

I'm using two AR7420 from TPLink modem, one for emulating a PEV and other the EVSE.

After a couple of days of modens powered by 12 Volts the communication stoped. I noticed that the IC AR7420 is really hot.

I'm trying to debug here, but the comunnication between PEV and EVSE isnt ...

Yes, both options make sense to me. The first seems simpler and faster to me, as I'm from Brazil and importing the module would cost a lot.

I have already purchased QCA and will probably assemble V1 of your project to evaluate how to change configurations. Using the TL-PA4010 adapters I already ...

Hey guys. I have been following the work developed on this topic and I am impressed by the rapid evolution. I would like to use the project as a basis to apply it to a vehicle charger.

The question is: Would it be possible to record the FLASH memory with the firmware of the SECC side? is it ...
