- Compact Smart Device Platform with Built-In Sensors
When building a portable sensor device, you normally need a display, input controls, motion sensing, audio input, battery support, and wireless connectivity. This board brings these functions together around XIAO nRF52840 Plus, allowing you to focus on the interface, sensor data, and device behavior instead of assembling separate modules and wires.
- Clear 1.14-Inch Display for Status and Simple UI
The 1.14-inch 135 × 240 IPS TFT display provides enough space for status pages, sensor readings, icons, menus, and lightweight animations. Together with three physical buttons, it allows you to build compact interfaces that remain easy and reliable to operate without requiring a touch screen.
- Voice, Motion, Buttons, and Grove I2C in One Board
The onboard PDM microphone can be used for sound detection, volume monitoring, or audio capture. The 6-axis IMU detects orientation, shaking, flipping, and motion, while three user buttons provide direct physical control. A Grove I2C interface makes it easy to add environmental, distance, light, and other compatible sensors without complex wiring.
- Built for BLE and Battery-Powered Projects
Powered by XIAO nRF52840 Plus, this version is designed for Bluetooth Low Energy and portable projects. It can connect to phones, computers, and gateways, making it suitable for wearable notifiers, BLE remote controls, portable sensor terminals, desktop devices, and motion-aware products that do not require Wi-Fi.
