The XIAO ESP32-C5 has emerged as a versatile addition to the ESP32 chip lineup, featuring dual-band Wi-Fi 6 support and a range of connectivity options. This compact board is designed for DIY enthusiasts looking to create interactive devices, such as a gesture-controlled desk buddy.
Overview of the XIAO ESP32-C5
The XIAO ESP32-C5 is notable for its support of both 2.4 GHz and 5 GHz Wi-Fi 6, along with Bluetooth 5 LE, Zigbee, and Thread protocols. This makes it suitable for various applications, particularly in environments crowded with smart devices. The board is powered by a 240 MHz RISC-V processor and includes 384 KB of SRAM, which is adequate for handling sensor data and running a small web server.
Components and Setup
For this project, a selection of Grove sensors was utilized, including a Digital Infrared Temperature Sensor, a Piezo Vibration Sensor, a Gesture Sensor (PAJ7620U2), and a Button. The temperature sensor measures both ambient and object temperatures, while the gesture sensor recognizes nine different gestures, enabling intuitive control of the device. The setup is simplified by the XIAO Expansion Board, which features an OLED display, microSD card slot, buzzer, and multiple Grove connectors, allowing for a solder-free assembly.
Functionality and User Experience
The gesture sensor stands out by enabling users to navigate through screens on the OLED display with simple hand movements. For instance, a wave to the right advances to the next screen, while a wave to the left returns to the previous one. Although the gesture recognition is responsive, the OLED display’s limited size requires careful formatting to convey information effectively.
Future Potential and Limitations
While the current project focuses on local functionality, the ESP32-C5’s dual-band Wi-Fi 6 capability remains untapped for networked features. The device’s design is still a work in progress, with plans for a 3D-printed case to improve aesthetics and organization. Despite these limitations, the XIAO ESP32-C5 and Grove ecosystem provide a robust foundation for further development, allowing for the addition of new sensors and features as needed.
