Product Descriptions

The ESP32-PICO series is a System-in-Package (SiP) device that is based on the ESP32 SoC. The ESP32-PICO series include ESP32-PICO-D4, ESP32-PICO-V3, and ESP32-PICO-V3-02 variants. In this document, unless otherwise stated, “ESP32-PICO” refers to all the variants.

ESP32-PICO provides Wi-Fi 802.11b/g/n, Bluetooth? v4.2 BR/EDR, and Bluetooth LE functionalities. It integrates all peripheral components seamlessly in a single package, including a crystal oscillator, filter capacitors, SPI flash/PSRAM (optional), and RF matching circuit. ESP32-PICO is built in an ultra-small size, with robust performance and low energy consumption. It is well suited for any space-limited or battery-operated applications, such as wearable electronics, medical equipment, sensors, and other IoT products.

The ESP32-PICO series of variants are similar to each other, but still vary in some aspects, for example, the embedded chip revision, pin layout, dimensions, etc. Table 1 lists the differences between these variants. For detailed description please go to specific sections.

If you would like to migrate from the existing module design based on older ESP32-PICO variants to a new design based on newer ESP32-PICO variants, please refer to section 13 Migration Guide.
