BassOwl Hat

[Darmur]

Dear VolumIO community,

some time ago I started to design my own Hat for Raspberry Pi and ASUS ThinkerBoard, powered by the TI TAS5825M stereo amplifier
ti.com/product/TAS5825M

This PCB is part of a bigger project, a VolumIO-powered Hi-Fi system with LCD touchscreen.

The board has also slots for adding two digital I2S microphones, for implementing an Alexa-like smart speaker.

It can be powered by a power supply ranging from 12V to 24V, and it will backpower the Raspberry Pi too, with all the required protections.

I’m very happy about the results, few days ago I got the pictures from the chinese PCB manufacturer, it looks great!

I should receive the first batch of 5 pieces within few days (parcel is already in Amsterdam), I really can’t wait to try it!

I’m writing this post to offer few pieces for free to someone willing to help me to create a proper driver. Something already exists (released by a TI application engineer), but most probably it will need some cleanup and adaptations to add microphone support.

Hi Dario,
is the BassOwl project still alive? Is there any way to get our hands on one of those boards? (Cost?) Seems like there are not a lot TAS5825M HATs out there…
Best,

Hi Pavlos,

I will check if I still have a few, I mostly used them as a present for friends and family.

Please be aware there is a bug in the driver I could not figure out how to solve it: on boot with Volumio the volume is always at 100%, even if the startup volume is set at a lower value in the playback options. Changing manually volume after boot works fine.
