+To run this example, you need a supported dev board connected to a JTAG adapter, which can come in the following forms:
 
 * [ESP-WROVER-KIT](https://docs.espressif.com/projects/esp-idf/en/latest/hw-reference/modules-and-boards.html#esp-wrover-kit-v4-1) which integrates an on-board JTAG adapter. Ensure that the [required jumpers to enable JTAG are connected](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/get-started-wrover-kit.html#setup-options) on the WROVER-KIT.
-* ESP32 core board (e.g. ESP32-DevKitC) can also work as long as you connect it to an external JTAG adapter (e.g. FT2232H, J-LINK).
+* ESP32 or ESP32-S2 core board (e.g. ESP32-DevKitC, [ESP32-S2-Saola-1](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/hw-reference/esp32s2/user-guide-saola-1-v1.2.html)) can also work as long as you connect it to an external JTAG adapter (e.g. FT2232H, J-LINK).
 
 This example will assume that that an ESP-WROVER-KIT is used.
