Espressif ESP32 S3 MINI-1-N8 AIoT WiFi & Bluetooth Module

The Espressif ESP32 S3 MINI run at up to 240MHz — a step above the LX6 used in earlier ESP32 families, with added vector instruction support that accelerates signal processing and on-device machine learning inference. The esp32 s3 carries 8MB of SPI flash in the N8 configuration, which is four times the storage of a standard 2MB variant. That extra space accommodates OTA update partitions, web server file systems, and TinyML model weights stored directly on the module without external memory chips.

A esp32 s3 mini wifi bluetooth module connectivity follows IEEE 802.11 b/g/n reaching up to 150Mbps throughput, while Bluetooth 5.0 LE supports both point-to-point connections and Bluetooth Mesh for multi-node sensor builds where devices relay data between themselves. The esp32 mini form factor uses a compact castellated footprint smaller than the WROOM 32 family — useful when PCB area is limited in a product design. Internal SRAM at 512KB handles runtime buffers, JSON parsing, and BLE stack data simultaneously without heap exhaustion under normal workloads.

The ESP32-S3 MINI does not include a U.FL connector or onboard PCB antenna on all variants. Confirm the antenna configuration of the specific sub-variant before ordering for range-sensitive enclosure builds. The ESP32-S3 mini 1 N8 pinout exposes GPIO, ADC, I2C, SPI, UART, and I2S through castellated pads. The WiFi Bluetooth module suits AIoT edge where TinyML and wireless connectivity are both needed on one board. Available on StemVolt. This ESP32 S3 MINI 1 module working on edge AI and builds compact wireless IoT Projects.
