Module Overview

1.2 Description

ESP32-PICO-MINI-02 and ESP32-PICO-MINI-02U are two general-purpose Wi-Fi + Bluetooth + Bluetooth LE

MCU modules. They are based on ESP32-PICO-V3-02, a System-in-Package (SiP) device, which integrates 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 two modules 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. ESP32-PICO-MINI-02U comes with a connector for an

external antenna. The ordering information of the two modules is listed as follows:

At the core of ESP32-PICO-MINI-02 and ESP32-PICO-MINI-02U 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.
