There are three versions of ESP32-S2 beta chip with different Wi-Fi PHY: A, B and Marlin3.
The correct setting is required for Wi-Fi to work correctly. If unsure which version you
have, please contact Espressif.
This setting must match the chip for Wi-Fi to work correctly. You can determine
the chip version by reading the markings on top of the chip. It will be one of the
three options given here.
The Wi-Fi performance of Marlin3 is the best among the three versions of chip.

The correct setting must be chosen in the project setting ``CONFIG_ESP32S2_BETA_CHIP_VERSION`` (found under Component Config -> ESP32S2-specific) for Wi-Fi to work correctly. If the selected version doesn't match the chip then Wi-Fi performance may be very poor, or the chip may crash when initializing Wi-Fi. If unsure which version you have, please contact Espressif.
.. important:: There are 3 versions of ESP32-S2 Beta engineering sample available with different Wi-Fi PHYs. They can be identified by the marking on the chip itself. The project must be configured to match the chip via the project setting "ESP32-S2 Beta chip version" (``CONFIG_ESP32S2_BETA_CHIP_VERSION``). This can be found under Component Config -> ESP32S2-specific. If the project setting doesn't match the chip then Wi-Fi performance may be very poor, or the chip may crash when initializing Wi-Fi.
