Wi-FiBluetoothSiPIoTDual-Core

The ESP32-PICO-D4 is a highly integrated System-in-Package (SiP) module that combines the powerful ESP32 dual-core processor with 4MB of flash, a crystal, and RF matching components, making it an ideal choice for space-constrained IoT designs.

Best for

  • Compact IoT devices
  • Wearable electronics
  • Battery-powered wireless sensors

Avoid if

  • Applications requiring external flash expansion beyond the integrated 4MB
  • Designs where a larger, non-SiP module is preferred for cost-optimization

Check before use

  • EN pin RC circuit
  • Reflow soldering temperature profile
  • Power supply stability
