Compact IoT development board

The LORDWORLD ESP32-S3 Mini is a dual-core microcontroller board aimed at hobbyists and engineers building wireless IoT prototypes. It ships with headers pre-soldered for immediate breadboard use. The Xtensa LX7 processor runs at up to 240MHz and integrates 2.4GHz Wi-Fi and Bluetooth 5 connectivity.

Check power and peripheral needs

Verify that your project can supply 5V via the USB Type-C port for programming and operation. The board exposes 34 GPIO pins with 4 SPI, 2 I2C, 3 UART, 2 I2S and 2 ADC channels; confirm the required interfaces match your sensors or actuators. Onboard memory includes 512KB SRAM, 384KB ROM, 4MB Flash and 2MB PSRAM.

Castellated edges and ceramic antenna

Castellated module edges allow the board to be soldered directly onto a custom carrier PCB for permanent deployment. The onboard ceramic antenna handles wireless signals without an external connector, saving space in tight enclosures. A USB serial controller provides a direct programming link from a host computer.
