Introduction: With the surging demand for edge computing, AI voice interaction, and high-speed connectivity in IoT devices, Espressif has launched its new ESP32-S31 series of chips. As a high-performance addition to its RISC-V architecture portfolio, the ESP32-S31 is emerging as the ideal choice for smart speakers, high-end home appliances, and industrial automation.
Currently, Shenzhen Mingjiada Electronics Co., Ltd., a professional distributor of electronic components, has taken the lead in making the ESP32-S31NR32V and ESP32-S31NR16V available in stock, providing robust supply support for major manufacturers and developers.
I. Key Highlights: A Comprehensive Innovation That Goes Beyond Connectivity
The ESP32-S31 is another major SoC launched by Espressif in 2026 following the ESP32-S3. It is not merely a wireless connectivity chip but a “jack-of-all-trades” that also boasts powerful edge AI capabilities.
1. Dual-Core RISC-V Architecture: A Quantum Leap in Computing Power
The ESP32-S31 features two 32-bit RISC-V processors clocked at up to 320 MHz, along with a built-in low-power coprocessor. One of the cores features a 128-bit data bus and supports SIMD instruction sets, meaning it outperforms traditional single-core architectures by a wide margin when handling audio encoding/decoding, image preprocessing, and lightweight AI/ML inference.
2. Full Support for Wi-Fi 6 and Bluetooth 5.4
Connectivity is a key strength of the ESP32-S31. It supports 2.4 GHz Wi-Fi 6 (802.11ax), which improves transmission efficiency and reduces power consumption in high-density environments; it also supports Bluetooth 5.4 (including LE Audio) and IEEE 802.15.4 (Thread/Zigbee), with native support for the Matter protocol, enabling seamless integration into smart home ecosystems.
3. Rich Multimedia and HMI Capabilities
Compared to previous models, the S31 significantly enhances human-machine interaction capabilities. It integrates a DVP camera interface, an LCD display driver (supporting 8–24-bit parallel), and up to 14 capacitive touch channels. Combined with the integrated JPEG codec and 2D graphics accelerator (PPA), the ESP32-S31 is ideal for developing interactive terminals with screens and voice capabilities.
II. Model Analysis: ESP32-S31NR32V and ESP32-S31NR16V
When selecting a product, in addition to the SoC core, the PSRAM and Flash configurations within the package are critical. The two models currently supplied by Shenzhen Mingjiada Electronics differ primarily as follows:
ESP32-S31NR32V: High-spec version. The chip package integrates a larger capacity of PSRAM (Pseudo-Static Random Access Memory), making it particularly suitable for scenarios requiring complex AI algorithms, high-refresh-rate display drivers, or large-capacity audio buffering.
ESP32-S31NR16V: Balanced Version. It integrates an appropriate amount of PSRAM or Flash configuration, achieving an excellent balance between cost and performance. It is suitable for standard IoT gateways, simple voice devices, or industrial sensors.
