Round 1.46in development board with colour touchscreen and onboard speaker microphone

LORDWORLD

LORDWORLD ESP32-S3 1.46in Round Display Board 412×412 16.7M Touch Audio

SKU CH-B4D6-1N8N9

A round 1.46 inch IPS display shows 16.7 million colours at 412×412 resolution with capacitive touch, onboard speaker, microphone and offline voice control for ESP32‑S3 projects

  • 46 inch round IPS display with 412 by 412 resolution and 16.7M colours
  • Capacitive touch via I2C with interrupt support for responsive UI
  • Onboard speaker and microphone enable high-quality audio I/O
  • Offline voice model allows device control through shortcut commands
  • Expansion via UART, GPIO and I2C for multiple peripherals

Round IoT Display Board

The LORDWORLD ESP32-S3 board integrates a 1.46 inch round IPS panel with a 412×412 resolution and 16.7M colour depth. Capacitive touch is managed over an I2C link with interrupt support for responsive UI interaction. An onboard speaker and microphone provide audio input and output, while an offline voice model enables command recognition without cloud connectivity. Makers building compact smart-home or wearable prototypes will find the integrated peripherals reduce wiring complexity.

Sustained Operation Behaviour

The QSPI display interface maintains stable frame delivery during continuous graphical updates, avoiding the bottlenecks common with slower serial screens. Audio processing runs on the ESP32-S3 dual-core processor, allowing simultaneous voice capture and playback without stalling the main application loop. I2C touch interrupts keep the CPU free for background tasks instead of polling. GPIO, UART and I2C expansion headers remain accessible for sensor arrays that stream data over long periods.

Upgrade Path And Limits

This board replaces separate display, touch and audio modules in projects that previously required multiple breakout boards and level shifters. The jump is worthwhile when a circular form factor and integrated voice control simplify enclosure design. Builders who need larger screen real estate or higher pixel counts for detailed graphics should look elsewhere. Projects demanding cellular connectivity or high-speed video streaming exceed the capabilities of this platform.

Questions about this item

Does the onboard speaker and microphone add audible fan-like noise or extra heat when the ESP32-S3 board runs continuously?

The board has no fan; the speaker and microphone are passive audio components, so they do not generate measurable noise or heat during all-day operation.

What power source must I already have to run this ESP32-S3 development board?

You need a USB cable and a 5 V USB power adapter or powered hub; the board draws power through its USB connector.

Can the UART, GPIO and I2C expansion headers on this board connect directly to my older sensor modules and serial devices?

The headers expose the ESP32-S3's UART, GPIO and I2C signals, so older sensors and serial devices that use those interfaces can be wired to the board.
