Waveshare ESP32-S3 Dev Board Supports WiFi/Bluetooth is a compact ESP32-S3 round-screen development board built for wearable devices, IoT terminals, smart home interfaces, portable HMI panels, motion-aware embedded projects, and round display applications. This board integrates the ESP32-S3R2, a 1.28-inch IPS round LCD, Wi-Fi, Bluetooth LE, QMI8658 6-axis IMU, and onboard battery charging support in a compact CNC metal enclosure. The ESP32-S3-LCD-1.28-B is a strong fit for projects that need both wireless connectivity and a small high-quality display. Its 240 x 240 round IPS screen, onboard QMI8658 accelerometer and gyroscope, and battery-ready design make it especially useful for wearables, portable interfaces, gesture-based applications, dashboards, and low-power connected devices. Features ESP32-S3R2 high-performance Xtensa 32-bit LX7 dual-core processor up to 240MHz. Supports 2.4GHz Wi-Fi and Bluetooth 5 LE with onboard antenna. 1.28-inch IPS round LCD with 240 x 240 resolution and 65K colors. QMI8658 6-axis IMU for motion and gesture sensing. 16MB Flash + 2MB PSRAM for display and wireless application development. USB Type-C for programming and serial communication. Onboard battery charge / discharge support for 3.7V lithium battery integration. CNC metal case with frosted acrylic back panel for compact product-ready design.

Packing List ESP32-S3-LCD-1.28-B x1 Screwdriver x1 Other Content Why the round LCD mattersThe 1.28-inch round IPS LCD makes this board a strong choice for projects that need a more product-like interface than a standard rectangular dev board. It works particularly well for watch-style UIs, circular dashboards, and compact visual status terminals. Motion-aware developmentThe onboard QMI8658 6-axis IMU adds gesture and orientation sensing, which helps when building wearables, motion interfaces, handheld devices, or interactive smart controls. Battery-ready wireless designWith onboard USB Type-C, battery charge/discharge support, and Wi-Fi + BLE, this board is well suited to projects that need to move beyond bench testing and into portable, low-power, connected product prototypes.
