Hi
You should not connect VIM4 to Tone2 Makers directly by 40-Pin Header,because the definitions of Tone2 Pin 7 and Pin 8 are different from VIM4.You can find the definitions of Tone2 40-Pin Header from the last page of schematic.
You can use both USB or I2S of the 40-Pin Header.The details are following below.
I’ve followed your pin out and the board now powers on correctly - however its not detected by the VIM4. Do I need to update something in relation to the ‘Operations from VIM4’ column and do you have instructions for this?
This firmware not right, it lead to your Tone2 back to factory test firmware, so it display"Tone2 Multichannel". you need to upgrade your Tone2 firmware to dual-v1.23. and then it will display"Tone2"
Hello. I’m trying to use the Tone 2 maket kit with the NanoPi NEO3 (Pure OS) via the GPIO by your instructions step by step, but it not work, can your help to me?
The Tone 2 works great with NanoPi NEO3 via USB C… (Firmware dual-v1.23)
Hi kenny,
Sorry, I mean USB connection. I tried using USB2.0 from the connector on the board and USB3.0 from the rear panel. The effect is the same. At this moment I have 5V power connected to pins 2 and 5 on the Tone2, USB connected to pins 3 and 4, pin 35 connected to the GND at pin 34, pin 37 supplied with 3.3V power through a separate linear regulator LDO1117. Input mode set to USB by encoder. It should be noted that there are no problems with this power supply, because the external coaxial input works perfectly - my factory Wiim Pro streamer plays music on this Tone2…
Hi kenny,
sorry for my late reply, I just returned from my long business trip.
I tried to connect as you showed me, but also did not see any effect. External USB type C still works great, it’s a shame that I couldn’t start the internal connection, apparently something is wrong with my Tone2…
