LORDWORLD ESP32-GEEK development board S3R2 1.14inch 65K LCD 16MB Flash

Compact IoT board for ESP32-S3R2 projects

The LORDWORLD ESP32-GEEK board targets hobbyists and engineers building Wi-Fi or Bluetooth LE devices with a built-in display. It integrates an Xtensa 32-bit LX7 dual-core processor running at 240 MHz, 512KB SRAM, 384KB ROM, 2MB PSRAM and 16MB Flash. The 1.14inch 240×135 pixel 65K colour IPS LCD provides immediate visual feedback without extra wiring. Integrated 2.4GHz Wi-Fi and BLE share one antenna through an internal coexistence mechanism.

Plug-and-play with headers and case

A plastic case and cables are included so the board can be used straight from the package. The 3-pin UART port, 3-pin GPIO header and 4-pin I2C port use standard pitch connectors that accept common jumper wires. No soldering is required for basic experiments, though the small header spacing may challenge users with limited dexterity. Online open-source demos and resources reduce the time needed to get a first sketch running.

Steady wireless throughput under load

The Wi-Fi radio operates in 1T1R mode with a maximum PHY rate of 150 Mbps and supports Station, SoftAP and combined Station + SoftAP modes. Bluetooth LE runs in a high-power 20dBm mode for extended range. The internal coexistence scheme arbitrates the shared antenna so sustained Wi-Fi traffic does not starve BLE connections. The dual-core processor and on-chip PSRAM keep the system responsive during continuous data logging or streaming tasks.
