Product details
Seeed Studio XIAO Nordic nRF52840 Sense Module
The ELECROW ESP32 Terminal is a compact IoT development device that combines an ESP32-S3 module, 3.5-inch SPI TFT capacitive touch display, and OV2640 camera in a single platform. Designed for beginners, students, makers, and professional developers, it provides the hardware and software flexibility needed to build interactive IoT, smart home, embedded, and computer vision projects.
The 3.5-inch 320 × 480 touch display provides a convenient interface for creating interactive dashboards, control panels, and custom graphical user interfaces. The integrated OV2640 camera adds support for applications such as image capture, face recognition, object recognition, and scene recognition.
With 2.4 GHz Wi-Fi and Bluetooth 5 (LE), the ESP32-S3 provides wireless connectivity for connected applications without requiring additional communication hardware. The terminal also supports Arduino, ESP-IDF, LVGL, PlatformIO, and MicroPython, giving developers multiple options for programming and UI development.
The built-in Crowtail interfaces make it easier to connect compatible sensors and modules, while interfaces such as UART, SPI, I2C, PWM, and I2S provide flexibility for hardware expansion. USB-C and polymer lithium battery power options also make the terminal suitable for both desktop development and portable IoT projects.
Why Choose This Board?
The XIAO Nordic nRF52840 Sense combines wireless connectivity, onboard sensing, processing capability, and low-power operation in a thumb-sized development board. Instead of requiring separate modules for basic motion and audio sensing, the integrated IMU and microphone provide these capabilities directly on the board.
Its compact form factor makes it particularly useful for wearable devices, portable sensor nodes, embedded Machine Learning projects, and other space-constrained applications.
