AI Summary

ESP32-WROOM-32-N4 by Espressif Systems: Bluetooth, WiFi Transceiver Module 2.4GHz ~ 2.5GHz Surface Mount.

The ESP32-WROOM-32E-N16 provides 16 MB of SPI flash memory while retaining the exact footprint, pinout, and electrical characteristics of the ESP32-WROOM-32 series. It is a drop-in option when additional code or data storage space is required.

  • Pin-compatible drop-in replacement
  • Quadruple SPI flash memory capacity (16 MB vs 4 MB)
  • Active lifecycle status

The ESP32-WROOM-32E-N4 is the official active direct successor to the ESP32-WROOM-32-N4. It features the updated ESP32-D0WD-V3 SoC while maintaining full pinout, footprint, and functional compatibility. It is an active product recommended for all new designs.

  • Pin-compatible drop-in replacement
  • Active lifecycle status with updated ECO V3 silicon fixes
  • Same 4 MB Quad SPI Flash and PCB trace antenna

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
