As per me previous post (https://www.reddit.com/r/homeassistant/comments/1g7tifn/esp32\_squeeze\_lite\_speakers\_across\_whole\_house\_on/), I only had a prototype of my ESP32 ceiling speaker, but now it’s fully soldered up PCB:

You can always read up on my blog post to catch up:

So yeah, this works like a charm. Some users wanted to see POE version and I’m working on it, but POE makes it much much and I repeat MUCH harder. there has to be hand shake with switch, Ethernet conversion and so on.

Basically now it’s done and I will make 4 more pieces to test latency and so on.

This pcb includes:

• HiLink 220v -> 12v converter for safe AC to DC conversion
• Certified Waggo smd connectors for both AC and Speaker side
• Small footprint
• 12v 30w Class D Power amplifier

Testing was a breeze after installing squeezeLite firmware and configuring it it just appeared as a device on LMS (Lyrion music server) and started working out of the box.

Things to still do:

• Test Power usage. (Right now it’s ~120mA on standby around 300mA under audio playback)
• Print 3D case for safety (AC is no joke my friends)
• Test with 6 devices to see load on network.
• Document everything on github
• Release all hardware PCB design on github
• Put contributions for all software used.
• Make V2 of the board
• POE version
• Test range of inbuilt antenna

I will document whole process over my blog at for you guys to read up and follow on.

As for now I’m a bit tired from work, so there will be some delay until those points sees the daylight.

if you have any tips or suggestions, please let me know, Any feedback is appreciated.

Thank you and I see you in no time!As per me previous post, I only had a prototype of my ESP32 ceiling speaker, but now it’s fully soldered up PCB:So yeah, this works like a charm.
