According to the model name it should have 8mb of psram. But the previous ans is it is not. Iam wondering...

Espressif ESP32-S3-WROOM-1-N16R8 Module does have 8MB of PSRAM. As it is an original product from Espressif you can be rest assured that the data is correct. The previous Question was discrepant.

R8 means 8MB PSRAM according to the datasheet. N16 means 16MB SPI FLASH. I can access 16MB flash memory, but not 8MB PSRAM. What is wrong. Does this really coming with 8MB PSRAM or Fake ?

ESP32-S3-WROOM-1 is powerful, generic Wi-Fi + Bluetooth LE MCU modules that are built around the ESP32-S3 series of SoCs. On top of a rich set of peripherals, the acceleration for neural network computing and signal processing workloads provided by the SoC make the modules an ideal choice for a wide variety of application scenarios related to AI and Artificial Intelligence of Things (AIoT), such as wake word detection, speech commands recognition, face detection and recognition, smart home, smart appliances, smart control panel, smart speaker, etc. ESP32-S3-WROOM-1 comes with a PCB antenna.

Package Includes:

1 x Espressif ESP32-S3-WROOM-1-N16R8 Module

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
