AI Summary

ESP32-S3-WROOM-1-N16R8 by Espressif Systems: Bluetooth, WiFi 802.11b/g/n, Bluetooth v5.0 Transceiver Module 2.4GHz PCB Trace Surface Mount.

The ESP32-S3-WROOM-1-N16R2 shares the exact footprint, 16 MB flash size, and PCB antenna of the target device while extending the ambient operating temperature range up to 85°C. However, it integrates 2 MB of Quad SPI PSRAM rather than 8 MB of Octal SPI PSRAM.

  • Pin-compatible drop-in replacement with identical 41-SMD footprint and PCB antenna
  • Same 16 MB flash memory capacity
  • Higher maximum operating ambient temperature (-40°C to 85°C vs -40°C to 65°C)
  • Reduced PSRAM memory capacity (2 MB Quad SPI vs 8 MB Octal SPI)

The ESP32-S3-WROOM-1-N4R8 provides a drop-in physical replacement retaining the 8 MB Octal SPI PSRAM and dual-core LX7 processor. It trades off flash memory, offering 4 MB instead of the 16 MB found on the queried part.

  • Pin-compatible drop-in replacement with identical 41-SMD footprint and PCB antenna
  • Same 8 MB Octal SPI PSRAM capacity
  • Lower cost option for smaller firmware footprints
  • Reduced flash memory capacity (4 MB vs 16 MB)

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.
