16 MB Flash and 8 MB PSRAM

The N16R8 designation identifies the module’s memory configuration: 16 MB flash and 8 MB PSRAM. Flash stores firmware and application assets, while PSRAM provides working space for tasks such as buffering sensor data or preparing graphics for a display. Select the matching flash and PSRAM settings in your development environment.

2.4 GHz Wi-Fi and Bluetooth Low Energy

Use the built-in 2.4 GHz Wi-Fi to send sensor readings to a dashboard or connect your project to a local network. Bluetooth Low Energy lets the board exchange data with compatible nearby devices, such as a phone running a BLE app. The board connects to 2.4 GHz Wi-Fi networks.

Soldered Headers and Project Wiring

The 44-pin count refers to the development board’s header layout, which includes power and ground connections as well as signal pins. Check the supplied board’s pinout when assigning connections for sensors, displays, or motor drivers. ESP32-S3 GPIO uses 3.3 V logic; check signal compatibility before connecting a 5 V peripheral.
