Overview
The ESP32-PICO-D4 is a System-in-Package (SiP) module developed by Espressif Systems. This module integrates the ESP32 chip, which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip, along with various peripheral components such as a 40 MHz crystal oscillator, 4 MB SPI flash, filter capacitors, and RF matching links. This integration makes the module highly compact and efficient, reducing the need for additional components and simplifying the supply chain and manufacturing process. The ESP32-PICO-D4 is designed using TSMC’s 40 nm ultra-low power technology, making it suitable for applications requiring low power consumption and robust performance.
