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:
