The AUCTUS A6 is the chip behind the inexpensive COTRE CO01D DMR radio. There isn’t much information available on the web. Here is what I was able to find.
COTRE CO01D now has documentation and CPS software to program it. All you need to add is a Baofeng style programming cable.
The COTRE CO01D is a real DMR radio capable of DMR Tier I and Tier II operation for cheap on Amazon.
