Waveshare ESP32-S3 7-inch Display Development Board Features 1024×600 Display, CAN, RS485, and Battery Monitoring

Waveshare has recently launched ESP32-S3-Touch-LCD-7B, an ESP32-S3-based 7-inch Display Development Board with a 1024×600 IPS display and optional capacitive touch support. It’s designed for rapid HMI development with Wi-Fi and Bluetooth connectivity, high-resolution GUI support, and multiple expansion interfaces, making it ideal for smart control panels, industrial displays, or embedded GUI projects.

The display supports 2.4GHz Wi-Fi, Bluetooth 5 (BLE), and includes interfaces like CAN, RS485, I2C, and an SD card slot for storage. The display supports 5-point capacitive touch (on the touch version) via I2C, along with interrupt support. It can run on battery, supports backlight control, onboard antenna, USB Type-C for power and data, and there are dual UART options for communication. The board features LED indicators for power and charge status, as well as support for real-time battery voltage monitoring and low-power modes.
