Compact IoT Development Board

The LORDWORLD ESP32-S3FH4R2 board delivers a 32-bit LX7 dual-core processor running at up to 240MHz with 2.4GHz Wi-Fi and Bluetooth 5 connectivity. It targets makers and engineers building wireless edge devices who need integrated radio and processing in a small footprint.

Solder-Ready Integration

Castellated edges allow the module to be soldered directly onto a custom carrier board, while the onboard ceramic antenna removes the need for external RF design. A USB Type-C port provides power and serial debugging, and 34 configurable GPIO pins expose 4 SPI, 2 I2C, 3 UART, 2 I2S and 2 ADC interfaces for peripheral expansion.

Sustained Low-Power Operation

Flexible clock control and independent power-domain settings let the board reduce consumption during long-running deployments. The 512KB SRAM and 384KB ROM support real-time tasks, while 4MB Flash and 2MB PSRAM store firmware and buffers without relying on external memory chips.

Preguntas sobre este artículo

How long can the dual-core processor sustain 240MHz before thermal limits reduce performance?

The board has no active cooling, so the Xtensa LX7 dual-core processor will throttle once its internal temperature rises under continuous 240MHz load.

What is the typical power draw and heat output when Wi-Fi and Bluetooth 5 run all day?

With 2.4GHz Wi-Fi and Bluetooth 5 LE active, the module draws modest current from the USB Type-C supply; the ceramic antenna and castellated design keep heat low enough for enclosed projects.

Which host interface must my computer provide to program and power the board?

A USB Type-C port on the host is required for both the integrated full-speed USB serial controller and the 5V supply rail.
