Sorry for the off-topic question. I followed in your footsteps and successfully tested the juice board using the FT2232 Learning Module. Thanks for a nice schematic/pdf file you shared. I am now looking forward to adding a filter board and TRX relay using my homebrew QRP labs 10W amp.
I want to use the arduino nano for controlling the filter board and TRX relay.
I am a bit confused about i2c lines ie (CN301, pin 17&18). Can the juice board directly control i2c ? I mean normally, this i2c is connected & handled by pi. Is it OK to use arduino nano for filter boards? Other i2c devices are a bit expensive here. Looking forward for some guidance.
Appreciate your time.
Thanks & regards

Hi Yoda-san,
Sorry, but I am a bit confused because of my limited skill set. About "radioberry-juice-i2c: line179- ....juice/i2c_bus.v", do I need to recompile gateware ie *.rbf, or just recompile "Radioberry-2.x/juice/firmware" on pi4.
If it's gateware, can I request you to share a .rbf file that will work with i2c based lpf.
Regarding pi3b, the juice board didn't work with it. Johan tried to help me with various inputs, but I could not get it to work. For a test, I pulled out a sd-card from pi3b and inserted it on pi4. Radioberry-juice worked fine on pi4. After re-inserting the sd-card back to pi3b, it didn't boot properly, as there were some changes made to the sd-card by pi4. My idea was to use pi3b to give a Lan support to the juice board, like HL2 & remotely operate within home network.
Thank you for taking time to reply.

Thanks for replying, I have no experience with working/compiling gateware. I will try to read/learn more about it. I am sure you will find some solution for pi3 in your free time. For now, I will focus on wiring lpf / trx & amp.
Appreciate your time.
