ESPRESSIF ESP32-S2-MINI-1U-N4

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. The ESP32-S2FH4 chip and the ESP32-S2FN4R2 chip at the core of the two modules fall into the same category, namely ESP32-S2 chip series (chip revision v0.0). 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:
