New(?) access control board

I buy stuff from AliExpress all the time just to try them out with my xSIID and magic rings…thought this was interesting so I gave it a go:

Not doing a formal review yet just because I haven’t had time, but it’s definitely interesting. Unlike the xAC and it’s HF clones, this board came with both 13.56mhz and 125khz antennas. The picture only shows the HF antenna attached, but it shipped with a secondary copper-wound antenna in the far left slot. It also accepts external configurable wiegand inputs, and also comes with a remote for programming. In quick testing between calls, I was able to confirm that it registers and works with both frequencies using a T5577, Mifare 1k, and the NTAG chip in my xSIID. I’ve got a dual frequency wiegand reader coming from AliExpress too that should be here any day…I’ll test it with that too.

Again, once I get a chance to do further testing I will, just thought this was neat. I haven’t seen a dual frequency version of the access control board before. I can also say in my brief test that it read my magic ring and xSIID very well through several layers of card stock that I had on hand…my other 13.56-only board won’t pick up my ring and has to have contact and a Hamspiced repeater to pick up my xSIID.

Let me know if this has been covered before. If not, stay tuned. Thanks.

Try some various UIDs changing a byte at a time. I bet you find something in the HF side that makes you go, “WHY?” If you don’t… Well, then we need to look closer at it. : )

I’ve seen the posts that they only check the last 4 bits or so…I’m assuming this will likely be similar.

I’ll try to do my due diligence with my flipper soon and will post the results.

And then there are the old classics: all bits on and off.

Can anyone check my code to make sure this doesnt happen on my diy acsess controller? Im sure i could knock togeather a small easily recreateable ac for cheap…

So…I changed the UID in this sequence for LF, and did the same thing with a 7 byte Mifare for HF (just added BB:CC at the end). The minute I shifted the AA byte to the second set the controller stopped accepting it. I tried all 5 variations (7 for HF) and it only accepted the original UID. Sounds promising? Any other tests you want me to perform? I didn’t quite understand your second one.

“AA:34:56:78:90”
“12:AA:56:78:90”
“12:34:AA:78:90”
“12:34:56:AA:90”
“12:34:56:78:AA”

You mean this?

Those are:

“00:00:00:00:00”
“FF:FF:FF:FF:FF”

If those don’t make the board act in weird and unexpected ways, let me and Tac0s know.

:wink:

Can confirm on both high and low frequencies that UIDs of solid 0’s or F’s were denied without any weird lights or effects.

I’m hoping to have the external reader by this weekend, will provide a formal review shortly.

Any chance this could be xAC V5? :grin:

Would be awesome to offer users the choice of frequency, and from what I can tell it would open up most implants as compatible. I’ll try to upload the programming booklet that came with it soon too…lots of good info there. And it’s mostly in good English this time.

Thanks for doing this.

I have just ordered one and will be replacing the controller I currently use for my home garage with this.

I appreciate your work.

Happy to be the guinea pig. Will continue to post more info as I test it. Let me know if there’s something you want me to look into as you’re waiting on China to ship.

I did find out this evening that there’s a remote command to turn off the piezo :partying_face:

Yep we ordered some test units

That explains why there was only a very limited number left.! Lol

Here’s the instructions that came with the unit. I confirmed today that it works great with the external wiegand reader I ordered. The reader’s performance is slightly better than the antennas that come with the board.

Image #6 since I can only upload 5 per post.

Initial poking at the test boards we got… They ignore the first byte of LF. Also, everything after the first four bytes of HF.

Here is the Flipper ir file for the remote.

Lost me a bit… so good or bad?

Balls. I thought I had tested that with the sequence above.

Bad. Same old problems.

Edit: I included the IR file because these boards always reference them but we’ve never had access to a remote.

Ok sorry brain not work good today…

I couldn’t tell it this was 90% of what we wanted or the exact same issue
