RE: Quality 5054a - apoelistas - 24-08-2017
One should ask the question with photo of both sides. For me this photo attached is of original amb2300. Not saying that there are no manufacturing revisions (this is version 1.2 only whereas there are newer versions 2.0 etc) This is important to check firmware upgrade and downgrade. Sixcode do you have a picture of back side??
RE: Quality 5054a - sixcode - 24-08-2017
Also like to know if this is a orginal, if you search ebay they ask 32 usd incl shipping...
this one is 10 usd

RE: Quality 5054a - apoelistas - 24-08-2017
check pdf pictures of oki. The original has 2 circles one with a mirror mark. Do you have amb2300 reverse side photo??
RE: Quality 5054a - sixcode - 24-08-2017
The One in the picture does have that. The other ones also.. but still.. 32 usd for a oki chip is a lot of money
Also if they make fake chips the mirror mark can be faked to....
RE: Quality 5054a - DTech - 24-08-2017
@sixcode - that is B model of oky used in old autocoms, so out of question for vas5054 even if it looks like ori just no mirror mark
@apoelistas - pictures of the back of that amb show you that it is fake. ori one has capacitors and resistences there, look in Fantomel's posts as he put some of the pictures to show all.
RE: Quality 5054a - sixcode - 24-08-2017
The bluetooth picture you posted have softing mark. I think that the Chinese don't have access to original board with BT module
Thanks for the pointer on B oki.
I see on ebay only oki chips with same serial number so I suspect these are fake also
what you think of this one:
