1.2 Description
ESP32-S2-WROVER is a powerful, generic Wi-Fi MCU module that has a rich set of peripherals. This module is
an ideal choice for a wide variety of application scenarios relating to Internet of Things (IoT), wearable electronics
and smart home.
This module is provided in two versions: one with a PCB antenna, the other with an Dipole antenna.
ESP32-S2-WROVER features a 4 MB external SPI flash and an additional 2 MB SPI Pseudo static RAM (PSRAM).
The information in this datasheet is applicable to both modules.
The ordering information on the two variants of ESP32-S2-WROVER is listed as follows:
