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.
