Hello, can I ask for help?
I recently purchased Amanero / Hermes / Cronus Combo boards for Buffalo III DAC. Connecting Cronus to BIII is made directly via a 20pin header (so there is no mistake when connecting). I coped with the change Amanero to Slave firmware etc.
After all NO LOCK :-(

I checked Amanero connected directly to BIII via I2S, with CPLD_for_1080 and it works correctly.

Then I checked the Cronos module and as you can see that when I give 5V power to the supply header of Cronus, I have not 3.3V voltage on the appropriate Cronus pins for the Hermes module.
Does this mean that the new arrived Cronus module is not working properly?

Some pictures are here:

Thanks in advance..
Marcin

I am still looking at the received Cronus v1.4 module and please correct me if I am wrong, but is the ADM1750 linear regulator not mounted the other way around? This is suggested by other photos of the Cronus module on the internet. In addition, I checked it with a multimeter according to the datasheet https://docs.rs-online.c...98/0900766b812c18ef.pdf. Do you agree with me?
