What are you reading? Silk-screened labels on the PCB, or markings

You certainly seem to be.
- I am reading each line of white printed text that is directly on the black I C chips
The chips are made by foxconn and I cannot find any information about the chips on their website
I need to know what frequencies each one of these chips can transmit and receive on
A18, A19, A20, A21, A81 are the bands / frequencies that are printed
The other numbers and letters means other things, like the 94-0
As you have linked the wiki article about
The 1109 must mean something
But the information I need is the bands of each chip
They used 2 different chips
So 3 of 1 chip are used and then 2 of the other chip are used
Thanks
