ESP32-S3-MINI-1
Overview
ESP32-S3-MINI-1 is a compact Wi-Fi and Bluetooth LE module from Espressif, designed for space-constrained designs that need wireless connectivity. It implements the ESP32-S3 family feature set (including on-chip accelerations useful for ML/edge inference) in a smaller module footprint to reduce PCB area and BOM complexity.
Why Choose This Part
The module delivers integrated 2.4 GHz wireless (Wi-Fi and Bluetooth LE) and key ESP32-S3 features in a smaller package that simplifies layout and reduces overall product size. Designers benefit from an integrated module (radio, crystal, flash options) to shorten time-to-market and reduce RF certification work, plus support for on-chip acceleration that helps with low-latency edge processing.
Applications
Getting Started
Use Espressif development kits (for example the ESP32-S3 DevKit series) or a carrier board/breakout that exposes the MINI-1 pins for evaluation. Develop with Espressif ESP-IDF (official SDK) or community cores such as the Arduino-ESP32 and PlatformIO; use the standard USB-UART programmer for flashing and the serial console for debug. Pay attention to antenna clearance, 3.3 V power supply stability, and required boot-strap pin states when designing a carrier PCB.
Dev Boards
Development boards and breakout modules featuring the ESP32-S3-MINI-1 or compatible chips — ready to use for prototyping.

Also Consider
Espressif Systems
- Larger S3-family module with more exposed I/O and a more feature-complete footprint for designs that need extra pins or interfaces.
Espressif Systems
- Smaller and lower-cost RISC-V based ESP32 variant for simpler IoT designs that need Wi-Fi and Bluetooth LE but not the S3-specific acceleration features.
