[arm-allstar] BF-888 new boards

Fri Apr 26 12:36:49 EDT 2019

Hi Fred.....

This file shows the 'old' new short board.  You probably have the 'new' new short board.  No 5 solder pads on bottom of board, but does have an IC chip instead..

The wire connections are the same, use the schematics that are attached in the file.  The attach points the same, and the COS chip is in the same location on the component side of the board.

I did this on mine and it works fine.

Hi guys,

Does anyone has an update on how to modify the new boards?
I just ordered a couple of BF-888 and they are shipped with these boards.

Tapping from the High side of volume control and mic line with some resistors to wiring COR right the op amp. I don’t need to worry about volume control on the knob, I adjust in the menu. Actually I took my volume knob off to fit it all in a small case.
