LORDWORLD

LORDWORLD ESP32-S3 Mini Development Board 2 PCS with Pre-Soldered Header

SKU CH-2281-KXD4A

Twin ESP32-S3 boards with pre-soldered headers, dual-core 240 MHz processor, 2.4 GHz Wi-Fi and Bluetooth 5, plus 34 GPIO pins for rapid IoT prototyping

  • Dual-core processor reaches 240 MHz for responsive IoT tasks
  • 4 GHz Wi-Fi and Bluetooth 5 enable wireless connectivity
  • 512 KB SRAM plus 384 KB ROM support larger firmware
  • 34 GPIO pins with multiple interfaces allow flexible peripheral wiring
  • Pre-soldered headers on two boards let you start prototyping immediately

Dual-Core ESP32-S3 Boards for Makers

This pack supplies two LORDWORLD ESP32-S3 Mini development boards, each built around a 32-bit Xtensa LX7 dual-core processor running at up to 240MHz. They arrive with headers already soldered, so prototypes can start immediately on a breadboard or custom carrier. Onboard 4MB Flash and 2MB PSRAM give room for firmware and runtime data.

Wi-Fi and Bluetooth LE Projects.

The 2.4GHz Wi-Fi 802.11 b/g/n and Bluetooth 5 LE radios suit sensors, home-automation nodes and wearable prototypes that trade bandwidth for range and power economy. Builders needing 5GHz Wi-Fi, Ethernet or cellular backhaul will need a different platform. The 512KB SRAM and 384KB ROM limit heavy local compute or large buffers.

Breadboard-Ready with 34 GPIO and USB-C

Castellated edges let the module be soldered directly to a carrier board, while the pre-soldered headers drop straight into a 0.1-inch breadboard. A USB Type-C connector provides power and the integrated USB serial controller for flashing and debug. Thirty-four configurable GPIO pins expose 4 SPI, 2 I2C, 3 UART, 2 I2S and 2 ADC channels for peripheral expansion.

Fragen zu diesem Artikel

What host computer interface is needed to program the board's USB serial port controller?

A USB Type-C port and cable are required to connect the board's integrated full-speed USB serial controller to the development host.

Will the board's 2.4GHz Wi-Fi 802.11 b/g/n radio coexist with older 2.4GHz Bluetooth peripherals?

Yes, the board supports Bluetooth 5 LE and 2.4GHz Wi-Fi on the same radio band, allowing simultaneous operation with legacy 2.4GHz devices.

How can I confirm the dual-core processor is running at 240MHz after flashing firmware?

Read the CPU frequency register via the serial console or log the configured clock speed from your firmware's startup routine.
