ESP32-Pico SoC, WiFi & BLE, 3.3 V, QFN-48 (7x7mm)

The ESP32-PICO series is a system-in-package (SIP) device that is based on the ESP32 SoC. The ESP32-PICO
series includes the ESP32-PICO-D4, ESP32-PICO-V3 and ESP32-PICO-V3-02 variants. In this document, unless otherwise stated,
the term "ESP32-PICO" refers to all 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. The 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
