Espressif ESP32 Pico Mini 02 8M Flash 2M PSRAM Module

ESP32-PICO-MINI-02 is a general-purpose Wi-Fi + Bluetooth + Bluetooth LE MCU modules. It is an 8 MB SPI flash, 2 MB SPI Pseudo static RAM (PSRAM) and 40 MHz crystal oscillator. The rich set of peripherals and a small size make the module an ideal choice for a wide variety of IoT applications, ranging from home automation, smart building, consumer electronics to industrial control, and they are suitable for intelligent speakers, speech recognition toys, intelligent gateway and Ethernet, etc. ESP32-PICO-MINI-02 comes with a PCB antenna. 

At the core of ESP32-PICO-MINI-02 is the ESP32-PICO-V3-02 sip*. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a low-power coprocessor 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. This ESP32 chip integrates a rich set of peripherals, ranging from SD card interface, capacitive touch sensors, ADC, DAC, Two-Wire Automotive Interface, to
Ethernet, high-speed SPI, UART, I2S, I2C, etc.
