ESP32-LyraT is an open-source development board for Espressif Systems’ Audio Development Framework (ADF). It is designed for smart speakers and smart-home applications. The dev board consists of the ESP32-WROVER-B module, a Micro SD card, expansion interfaces, touch buttons and several function keys.
With a great variety of voice commands, interactive voice functions and a rich peripheral set, ESP32-LyraT allows the fast development of applications relating to consumer electronics, wearables, smart home and industrial automation.
It facilitates the quick and easy development of dual-mode (Bluetooth + Wi-Fi) audio solutions , also supporting one-key Wi-Fi configuration, a wake-up button, voice wake-up, voice recognition, cloud platform access, and an audio player.
- ESP32-WROVER Transceiver
- 802.11 b/g/n (Wi-Fi, WiFi, WLAN)
- Bluetooth® Smart Ready 4.x Dual Mode 2.4GHz Evaluation Board

This is the latest development release of CircuitPython that will work with the ESP32-LyraT.
Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.
Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
