This allows flexible adaptation to storage requirements across different scenarios, eliminating the need for complex additional storage modules and simplifying device hardware design. It also supports concurrent access to Flash and PSRAM, enhancing data read/write efficiency.

- Comprehensive multi-protocol connectivity: Integrates Wi-Fi 6, Bluetooth 5.4, IEEE 802.15.4 and Ethernet MAC, enabling seamless integration into the Matter smart home ecosystem to achieve cross-device local interconnection. It is also compatible with traditional Bluetooth devices, balancing high-speed wireless transmission with low-power requirements to suit diverse scenarios such as wireless communication and remote control, covering mainstream IoT ecosystems.

- Extensive peripheral and interaction capabilities: Equipped with 61 GPIO pins, supporting DVP camera interfaces (8–16-bit), RGB LCD interfaces (8–24-bit) and 14 touch channels. It also integrates a variety of peripheral interfaces including USB OTG, SPI, I2S, UART, I2C, LED PWM and TWAI (CAN 2.0), enabling direct connection to external devices such as cameras, displays and sensors to meet complex human-machine interaction and data acquisition requirements.

- Comprehensive security safeguards: Utilising multi-layered hardware security mechanisms, it supports secure boot, Flash/PSRAM encryption, ECDSA digital signatures, RAM-based PUF and hardware encryption acceleration. It offers protection against side-channel attacks and power-failure injection, whilst integrating a Trusted Execution Environment (TEE) and Access Policy Management (APM) to ensure data security and operational stability, meeting stringent industry security standards.

As a balanced product, the ESP32-S31NR16V achieves an optimal balance between performance and cost. It is widely used in standard IoT gateways, simple voice devices, industrial sensors, smart wearables, Bluetooth remote controls and various other devices, making it an ideal choice for the R&D of mid-to-high-end IoT products.
