Hi everyone, what's the best/easiest way to connect the FifoPi Q7 with an I2S signal?
My need is to have a Bluetooth dac, so I will use a Bluetooth to I2S(perhaps slave) receiver, somehow connect it to FifoPiQ7 and so I can have clean output to the dac chip, all in one box.
Looking at the datasheet for FifoPiQ7 it accepts I2C but not I2S and I don't want to use a Pi at all. I've looked at the ReceiverPi Pro but there's no easy I2S input pins and I'm not 100% I can use it without an actual PI.

I have music! 
Next, I will connect UcPure and UcConditionner. And fix all this on a board for easier transport.
Thank you @iancanada for your quick reply!

New ES9038Q2M DM MKII best sound quality configuration
I have been testing this new ES9038Q2M Dual Mono MKII DAC for more than two weeks. I’m really happy with it.
I tried many configurations. They are all excellent. Based on my test, the best sound quality configuration is:
#4B ES9038Q2M Dual Mono MKII DAC DAC
#6B OPA861 I/V
#1D FifoPiQ7 with SC-Pure 45 and 49
#32B LinearPi Solo 5V with #25B UcConditioner 5V
#41C UcPureMkIII 3.3V for both Q7 and DAC (two UcPure3.3V could be even better)
#41C 2*UcPureMkIII 5V for I/V
#49B MonitorPiPro as controller
RaspberryPi 4
#35B StationPiPro (optional)
#19C ReceiverPiProII with controller (optional)
USB streamer (Amanero or compatible, optional)
The recommended MonitorPiPro or ESS controller configuration with SC-Pure 45/49:
ES9038Q2M Dual Mono MKII DAC has more improvements over the previous version.

But the SC-Pure clocks and UcPure MkIII power supplies (with 3000F UCs) also make big differences.
It could be the best sound quality Sigma-Delta DAC so far I have ever listened to. I even couldn’t decide which one I prefer when compared with my Spring3 (Drive be my external DDC with the same SC-Pure clock upgrade). They are both great. The Spring3 is one of the best R2R that I highly recommend. It sounds a little bit more dynamic. However, the ES9038Q2M DM MKII sounds more musical and delicate, especially for violin and vocal.
Please see the attached picture for the system under testing. I’ll order a case next to make it a well finished DAC.

ReceiverPiPro can receive i2S over hdmi port - that’s the i2S interface to it. See my DAC build
I have this DAC board and it’s working great with FiFoPiQ7 with SCPure clocks powered by UCPureMkIII- now all soaked in. And the power blocks are more convenient.New ES9038Q2M DM MKII best sound quality configuration

I haven’t gone UCPure for the output board but I have linear pi duo for compactness.
Hi @iancanada
Regarding your MonitorPi Pro controlling the StationPi Pro.
Can the DDC Control of the MonitorPi also be used to control the input selection on the StationPi Pro?
PS: your new mkII ES9038 looks really nice🙂

Hi Ian
Do you plan to have a build in ESS controller with volume control in the new StationPi pro controller? 🙂

They looks great on your system.
But please be very careful never reverse the orientation, otherwise the baby can get damaged.

Oh yeah! I know. Round circle ⭕️ on case is pin 1 and you match that with the circle mark on PCB near one corner of socket.
