  • Flexible integration using CAN, RS485, I2C and isolated IO
  • Bottom or back wiring with two screw terminal types included

IoT Edge Board with 4.3inch IPS Touch

The LORDWORLD development board integrates an ESP32-S3 dual-core processor with a 4.3inch IPS display at 800×480 resolution. It provides a 160° wide viewing angle and a 5-point capacitive touch panel driven over I2C. The board ships inside a plastic case and includes screw terminals for two wiring orientations.

Makers needing CAN and RS485 expansion

Engineers building industrial HMIs or DIN-rail gateways will appreciate the onboard CAN, RS485, I2C and isolated IO interfaces. Buyers who want more storage or a larger screen area should look at something else. Projects requiring cellular connectivity or Power-over-Ethernet are not served by this hardware.

Sustained operation with dual-core 32-bit LX7

The 32-bit LX7 dual-core processor maintains responsiveness during continuous UI updates and peripheral polling. WiFi at 2.4GHz and BLE 5 remain stable during long data-logging sessions. The included case aids heat dissipation so the board runs reliably in embedded enclosures.

Questions about this item

What power supply do I need to run the 4.3inch 800×480 IPS display and ESP32-S3 board?

Provide a 5 V DC source capable of at least 1 A through the onboard USB-C connector; the board regulates power for the display and processor internally.

Can I keep my existing RS485 sensors and connect them to the CAN and RS485 ports on this board?

Yes, the board exposes both CAN and RS485 screw-terminal interfaces so legacy RS485 devices can be wired directly without extra converters.

How can I verify the 5-point capacitive touch and 160° viewing angle are working after I flash my firmware?

Run a touch calibration sketch that reports five simultaneous touch points, then view the IPS panel from extreme side angles — colours should stay consistent across the 160° range.
