u-blox NORA-W106-10B
Stand-alone radio module embedding an ESP32-S3 SoC with a built-in antenna and 8 MB embedded Octal SPI PSRAM; soldered as component M1 on the Arduino Nano ESP32. Not a user-replaceable module family, and not assembled from the Espressif WROOM/WROVER lines.
The NORA-W106-10B is u-blox’s stand-alone radio module embedding an ESP32-S3 SoC, a built-in antenna and 8 MB embedded Octal SPI PSRAM. On this site it appears as component M1, soldered on the Arduino Nano ESP32 — it is not a user-replaceable module family, and it is not part of the Espressif WROOM/WROVER lines even though the chip inside is Espressif’s.
Start from the board: Arduino Nano ESP32 — see the pin numbering guide before wiring.
What this module decides on that board
- PSRAM lives here — the 8 MB Octal PSRAM is inside the module; the board’s 16 MB flash is a separate on-board chip (U3). That split is the reverse of the WROOM pattern where both memories sit in the module.
- Radio and antenna — Wi-Fi and Bluetooth LE through the module’s built-in antenna; silicon limits stay on the ESP32-S3 chip page.
Also known as: nora-w106, nora-w106-10b, nora w106.
