This project is based on the HiFi version of the ESP32 Audio Dock, in fact it shares a lot with it. But it adds a few important extras.
Most noticeably it adds an aluminum case which adds a much more finished look, compared to the bare pcb module. I had a custom back panel that exposes the most important board interfaces.
- USB-C port for power, flashing and debugging
- Line level audio output. You can drive headphones with it, as well as connect to your stereo system, like a traditional pre-internet amplifier.
- Wi-Fi antenna connector. (As you may imagine perception is not so good inside alu case)
- 5V Relay output driver controlled by GPIO (if you wish to switch your external amp off, when device goes to sleep).
It uses an off-the-shelf ESP32-WROVER module that includes a PSRAM chip, which is basically mandatory for internet streaming projects.
It is designed primarily to be used with the squeezelite-esp32 software, which is a brilliant way to enter streaming era using low-power device, like ESP32
I'm planning to add a transparent front panel, therefore the OLED screen and RGB led are in WIP state, but it is possible to connect and use them.
So I just spent the last 20 minutes RTFM'ing, and this really needs a QuickStart guide. I have been attempting to connect to it via my phone, and I'm blocked by a wifi password. Bluetooth is not showing anything at all, so no dice there either. Cannot find how to use this standalone (not setting up with HA) anywhere in your documentation. I know this is probably basic stuff, but we need to know the basic stuff somehow.
