The ESP32-S2-MINI-2 and ESP32-S2-MINI-2U are versatile Wi-Fi MCU modules with powerful features and a wide range of peripheral interfaces, suitable for applications such as wearable electronics and smart home devices. The ESP32-S2-MINI-2 uses a PCB onboard antenna, while the ESP32-S2-MINI-2U features an IPEX antenna. Both modules are equipped with 4 MB of SPI flash and are powered by the ESP32-S2FN4 chip. The ESP32-S2FN4 chip is based on the Xtensa® 32-bit LX7 single-core processor, running at a frequency of up to 240 MHz. Users can turn off the CPU and utilize the low-power co-processor to monitor peripheral status changes or detect whether certain analog thresholds are exceeded. The ESP32-S2-FN4 also integrates a wide variety of peripheral interfaces for flexible connectivity and control.
