ESPRESSIF ESP32-PICO-D4

ESP32-PICO-D4 is an ESP32-based SiP module that provides complete Wi-Fi and Bluetooth functionality. The module measures only 7.000±0.100 mm × 7.000±0.100 mm × 0.940±0.100 mm and integrates one 4MB SPI flash. At the core of ESP32-PICO-D4 is the ESP32 chip — a single-chip solution integrating 2.4GHz Wi-Fi and dual-mode Bluetooth, fabricated with an ultra-low-power 40nm process. The ESP32-PICO-D4 seamlessly integrates all peripheral components within the package, including a crystal oscillator, flash, filter capacitors, and RF matching network, eliminating the need for any external components. As a result, module soldering and testing steps are also avoided, significantly reducing supply chain complexity and improving management efficiency. With its compact form factor and low power consumption, ESP32-PICO-D4 is well-suited for space-constrained or battery-powered applications such as wearables, medical devices, sensors, and other IoT devices.
