Espressif systems has announced ESP32-S2 MINI-1U with IPEX antenna and ESP32-S2-MIN-1 with a PCB antenna the breed of a newly branded ESP32-S2 WIFI modules part of Mini series modules.
These are new additions to the catalog of Espressif systems which includes the ESP32-S2 Development boards, Espressif’s ESP32-S2 Wi-Fi Soc with future release of ESPS32-S3 and ESP32-C3 processors and much more both in software and hardware. The company describes the two modules as “two powerful, generic Wi-Fi MCU modules with a rich set of peripherals.” The two modules are only different in size and antenna type, but share similar specs
At the core of the ESP32-S2-MINI modules are ESP32-S2FH4, which is an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz. This chip has a low-power co-processor that can be used instead of the CPU, in order to save power while performing tasks that do not require much computing power, such as the monitoring of peripherals.
ESP32-S2FH4 has up to 43 GPIOs and integrates various peripherals, such as SPI, I2S, UART, I2C, LED PWM, LCD, camera interface, ADC, DAC, touch sensor, and temperature sensor. ESP32-S2FH4 also includes a full-speed USB On-The-Go (OTG) interface which enables USB communication in any place, at any time. The modules are the ideal choice for a wide variety of application scenarios relating to the Internet of Things, wearable electronics, and smart home.
