Just last week, we wrote about Espressif ESP-ADF Audio development framework that can be used to develop smart speakers and other audio applications with ESP32 boards.
There was only one board with documentation at the time however: ESP32-Lyra-T. One tiny problem: it was not for sale just yet, but today Olimex has announced the board is in stock, selling it for 22 Euros.
Main features:
- Wireless module – ESP32-WROVER module with WiFi and Bluetooth LE
- Audio
- Many audio inputs – Wi-Fi, BT-audio, DLNA, 3.5mm audio Line-in
- 3.5mm headphone jack
- 2x microphones
- Speaker connectors
- Storage – micro SD slot
- Debugging – JTGA header, USB UART
- Misc – Touch sense buttons, function/boot/reset keys, DIP switch for configuration
- Power – 5V via micro USB port; battery header + charger chip
You’ll find documentation on Espressif website (user guide) as well as on Github’s ESP-ADF (getting started guide).

“Display – LCD connector”
“Camera – Camera connector”
Neither of these appear to be present on the board.
Those are SPI connected, so you would change the mode of the JTAG connector. This is a tiny $1 SOC, it does not have full blown camera and LCD support.
If you want a video capable camera and display this is not the right chip for you.
There are a few mistakes on Olimex product page, maybe due to copy/paste from another board. I corrected the module part number, but in a rush, I missed those two.
Olimex also started to sell ESP32-LyraTD-MSC audio mic HDK with ZL38063 for 44 Euros.
