                Hi,   I just received the Buffalo III SE Pro board with the 2x Trident 3.3 Volt supply.   From my understanding,  the VD is powering both the Trident.   I have the following questions. 1) is each Trident powering the left channel and another Trident powering the right channel of the ES9038pro chip ? 2) I am going to remain using all the supplied regulators of the kit.    But I would like to have separate VD (5V) to power each Trident separately.  Is that possible ?   Alan Edited by user Tuesday, April 20, 2021 6:32:21 AM(UTC)

                Hi, 
  I have studied the board in more detail.   I asked the wrong question above.   I am referring to the dual AVCC 3.3V regulator instead of the two 3.3V Trident.   Also I figured that I can remove that particular jumper pin marked as  'in'  to the AVCC module and then I can connect separate 5V power supply to those two 'in' to achieve separate supply to the left and right AVCC regulator.

                That is correct.  Make sure you shared grounds.
