  • Espressif’s ESP32-S2-MINI series comprises of two new Wi-Fi MCU modules operating on the ESP32-S2 chip
  • Ideal for a wide variety of IoT, wearable electronics and smart home applications

Espressif has announced the inclusion of two new modules to its ESP32-S2-MINI series of modules: the ESP32-S2-MINI-1 and the ESP32-S2-MINI-1U that are powerful, generic Wi-Fi MCU modules with a rich set of peripherals, making them an ideal choice for a wide variety of applications relating to the Internet of Things, wearable electronics and smart home.

ESP32-S2-MINI-1 has a PCB antenna, while the ESP32-S2-MINI-1U has an IPEX antenna, both featuring a 4-MB embedded SPI flash.

The core of ESP32-S2-MINI modules is the ESP32-S2FH4, 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 for saving power while performing tasks that do not require much computing power, such as peripheral monitoring.

The 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. It also includes a full-speed USB On-The-Go (OTG) interface for enabling USB communication.

Currently, ESP32-S2-MINI-1 and ESP32-S2-MINI-1U are undergoing FCC, CE, SRRC certifications for full compliance with the health, safety, and environmental protection standards set by the United States’ Federal Communications Commission, the European Economic Area and the State Radio Regulations of China, respectively, which is expected to get completed by the end of November 2020.

The modules and development boards will then go into mass production in December 2020 and available in dimensions
(15.40±0.15)x(20.00±0.15)x(2.40±0.15) for ESP32-S2-MINI-1 and (15.40±0.15)x(15.40±0.15)x(2.40±0.15) for ESP32-S2-MINI-1U with modules from the ESP32, ESP32-S3 and ESP32-C3 series to be also included in the MINI series later.
