What commenters say

• The ESP32-C6 is available for purchase, but its software and SDK are still under active development.
• The ESP32-S3 has native USB support, allowing it to emulate other classes of USB devices.
• The ESP32-C3 has built-in USB serial/JTAG functionality, but it is limited to programming and debugging, and does not support making custom USB devices.
• The RISC-V architecture of the ESP32-Cx series is an advantage due to its open nature and long-term support.
• The ESP32 boards from Lilygo are a good option for some users, but others have had mixed experiences with their products.
• The ESP32-S2 is not necessarily an older version of the ESP32-S3, but rather a different model with its own features and applications.
• The AI support on the ESP32-S3 is not clearly defined, and more information is needed to understand its capabilities.
• The ESP32 boards can be used for a wide range of applications, including smart home devices, wireless sensors, and machine learning projects.
