ESP32-PICO-MINI-02U
ESP32-PICO-MINI-02U is a small-sized powerful Wi-Fi+Bluetooth®+Bluetooth® LE MCU module. It is 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 oscillator. This module targets a wide variety of IoT applications, ranging from home automation, smart building, consumer electronics to industrial control, and it is suitable for intelligent speakers, speech recognition toys, intelligent gateway and Ethernet, etc.
ESP32-PICO-MINI-02U Module Variants
ESP32-PICO-MINI-02U-N8R2
The ESP32-PICO-MINI-02U-N8R2 delivers all the power of the PICO-MINI-02 in an ultra-compact package, but with one key upgrade-an external antenna connector (U.FL/IPEX) for maximum wireless flexibility. This allows you to choose the right antenna for your application, boosting range and improving signal reliability in tough environments.
Inside, you’ll find 8MB of flash and 2MB of PSRAM, giving you plenty of storage for firmware, graphics, or data, plus the memory needed for demanding tasks like real-time audio processing, video streaming, or edge AI. Its PICO architecture integrates the ESP32 SoC, flash, crystal, and other key components into one small footprint, simplifying PCB design and reducing overall device size.
Compared to larger ESP32 modules like the WROOM or WROVER, the PICO-MINI-02U is designed for projects where every millimeter counts-but where wireless range and reliability still matter. Think portable electronics, embedded controllers inside metal housings, or long-range IoT sensors.
In short-ESP32-PICO-MINI-02U-N8R2 gives you big performance in a tiny form factor, with the freedom to optimize wireless connectivity for your specific deployment.
Note: Variants may have different features, flash sizes, and PSRAM configurations. Check the individual module pages for detailed specifications.
