2.4 GHz WiFi module Espressif ESP32S2MINI1 and Espressif ESP32S2MINI1U

ESP32-S2-MINI-1 and ESP32-S2-MINI-1U are two powerful, generic Wi-Fi MCU modules that have a rich set of peripherals. They are an ideal choice for a wide variety of application scenarios related to Internet of Things (IoT), such as wearable electronics and smart home.

ESP32-S2-MINI-1 comes with a on-board PCB antenna (ANT), and ESP32-S2-MINI-1U with an external antenna connector (CONN). Both ESP32-S2-MINI-1 and ESP32-S2-MINI-1U have three variants:
• integrating the ESP32-S2FH4 chip (which is embedded with a 4 MB high-temperature flash), and operating at –40 ∼ 85 °C
• integrating the ESP32-S2FH4 chip (which is embedded with a 4 MB high-temperature flash), and operating at –40 ∼ 105 °C
• integrating the ESP32-S2FN4R2 chip (which is embedded with a 4 MB flash and 2 MB PSRAM), and operating at –40 ∼ 85 °C

In this datasheet unless otherwise stated, ESP32-S2-MINI-1 refers to ESP32-S2-MINI-1-N4, ESP32-S2-MINI-1-H4 and ESP32-S2-MINI-1-N4R2, whereas ESP32-S2-MINI-1U refers to ESP32-S2-MINI-1U-N4, ESP32-S2-MINI-1U-H4 and ESP32-S2-MINI-1U-N4R2. The ESP32-S2FH4 chip and the ESP32-S2FN4R2 chip falls into the same category, namely ESP32-S2 chip series. ESP32-S2 series of chips has an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz. It has a low-power co-processor that can be used instead of the CPU to save power while performing tasks that do not require much computing power, such as monitoring of peripherals.
ESP32-S2 series integrates a rich set of peripherals, ranging from SPI, I2S, UART, I2C, LED PWM, TWAI®, LCD, Camera interface, ADC, DAC, touch sensor, temperature sensor, as well as up to 43 GPIOs. It also includes a full-speed USB On-The-Go (OTG) interface to enable USB communication.
The ESP32-S2FH4 chip and the ESP32-S2FN4R2 chip vary in:
• temperature of embedded flash
• whether a PSRAM is embedded
