The LORDWORLD development board combines an ESP32-S3 microcontroller with a 1.54 inch black-and-white e-paper display at 200 × 200 resolution. Onboard audio codec hardware enables high-quality audio input and output. The platform supports Wi-Fi and BLE dual-mode communication for cloud connectivity. It is designed for makers building voice-enabled IoT prototypes.

Makers adding voice to e-paper projects

Developers who want AI speech interaction with online large-model platforms such as DeepSeek and Doubao will find the SDK and tutorials helpful. The board also supports temperature and humidity monitoring for environmental sensing. Builders needing a colour display, higher refresh rates, or cellular connectivity should consider other hardware.

200 × 200 e-paper resolution

The 1.54 inch display provides a 200 by 200 pixel canvas that determines text clarity and graphic detail for e-reader or dashboard use. This fixed resolution is the key specification when deciding if the screen meets your project's visual requirements.
