About this product
Overview
The IoTCrazy ESP32-S3 Mini packs a lot of capability into a very small board. It is built around the ESP32-S3FH4R2, whose dual-core Xtensa 32-bit LX7 processor runs at up to 240 MHz — enough headroom to keep multi-threaded IoT applications running smoothly.
Wireless is native: 2.4 GHz Wi-Fi and Bluetooth 5 (LE) with an on-board ceramic antenna for stable transmission. Memory is generous for a board this size — 512 KB SRAM, 384 KB ROM, 4 MB flash and 2 MB PSRAM — which comfortably covers heavy code, sensor data logging and small on-device machine-learning workloads.
The castellated module design matters if you plan to go further than a breadboard: the same board that carries your prototype can be soldered straight onto a custom carrier PCB, so you never have to re-architect the hardware for production. Supplied as a 2-pack.
Key Features
- 2-pack, dual-core power — Two boards, each with an Xtensa 32-bit LX7 dual-core processor at up to 240 MHz
- Seamless wireless — 2.4 GHz Wi-Fi and Bluetooth 5 (LE) with an on-board ceramic antenna
- Ample memory — 512 KB SRAM and 384 KB ROM, plus 4 MB flash and 2 MB PSRAM
- Castellated edges — Solder the module directly onto your own carrier board for a finished product
- Modern USB-C — Fast programming and power delivery over a reversible connector
- Low-power friendly — Flexible clocking and independent module power configuration for battery-powered designs
