ESP32S2 WiFi 802.11b/g/n Transceiver Module: Datasheet, Pinout, and Application

ESP32-S2 family is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes. ESP32-S2 family includes a Wi-Fi subsystem that integrates a Wi-Fi MAC, Wi-Fi radio and baseband, RF switch, RF balun, power amplifier, low noise amplifier (LNA), etc. The chip is fully compliant with the IEEE 802.11b/g/n protocol and offers a complete Wi-Fi solution. At the core of this chip is an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz. The chip supports application development, without the need for a host MCU. The on-chip memory includes 320 KB SRAM and 128 KB ROM. It also supports multiple external SPI/QSPI/OSPI flash and external RAM chips for more memory space.
