LORDWORLD ESP32-S3FH4R2 Development Board 2MB PSRAM 4MB Flash

SKU CH-PMYM-K3Y7A

A compact IoT development board with a dual-core 32-bit LX7 processor at 240 MHz, 2 MB PSRAM, 4 MB Flash, 2.4 GHz Wi-Fi and Bluetooth LE, plus 34 multi-function GPIO pins

  • Dual-core 32-bit processor runs at 240MHz for responsive IoT tasks
  • 2MB PSRAM plus 4MB Flash give ample room for code and data buffers
  • 34 multi-function GPIO pins let you connect sensors, displays and actuators directly
  • Integrated 2.4GHz Wi-Fi and Bluetooth LE provide wireless connectivity out of the box
  • Multiple low-power modes help extend battery life in portable projects

Compact ESP32-S3 development board

The LORDWORLD board uses an ESP32-S3FH4R2 chip with a Xtensa 32-bit LX7 dual-core processor running up to 240MHz. It provides 512KB SRAM, 384KB ROM, 2MB PSRAM and 4MB Flash. Integrated 2.4GHz Wi-Fi and Bluetooth LE give wireless connectivity. An FPC 8-pin connector allows USB Type-C via an adapter board.

Makers and IoT prototypers needing dual-core

Suits developers building connected sensors, smart-home nodes or battery-powered edge devices that rely on 2.4GHz Wi-Fi and Bluetooth LE. The 34 multi-function GPIO pins support SPI, I2C, UART, ADC and PWM for flexible peripheral interfacing. Multiple low-power states help balance range, data rate and consumption. Not for projects that require 5GHz Wi-Fi or wired Ethernet connectivity.

34 GPIO pins with SPI, I2C, UART, ADC and PWM

The board exposes 34 multi-function GPIO pins covering SPI, I2C, UART, ADC and PWM peripherals. This pin count and interface mix determines whether the board can accommodate the sensors, displays or actuators a design needs. Check the required peripheral count against the 34 available pins before committing.

Questions about this item

How often will the 4MB Flash memory need replacement under repeated firmware updates?

The onboard 4MB Flash is rated for many thousands of erase cycles, so typical development workloads will not wear it out during the board's useful life.

Which limit appears first when the dual-core processor runs continuously at 240MHz?

Thermal throttling from the Xtensa 32-bit LX7 dual-core chip is the first constraint under sustained 240MHz operation.

How much heat does the board produce when Wi-Fi and Bluetooth LE run all day?

With integrated 2.4GHz radio active, the module stays warm but within the ESP32-S3FH4R2's specified operating temperature range.
