- Espressif ESP32-S3 - Use software that uses Espressif ESP-IDF v5.0.0 or later. When using versions of the Espressif ESP-IDF SDK _older_ than v5.0.0, ESP32-S3 has problems with I2C devices that do clock stretching or have other unusual timing behavior. ESP-IDF is the underlying software used by CircuitPython and the Arduino `esp32` board support package. CircuitPython 9.0.0 and later and Arduino `esp32` v5.0.0 and later use ESP-IDF v5 and later. These versions support most I2C devices well. However, some of the troublesome chips listed above still don't work well or at all even with ESP-IDF v5.
