The AS608 Optical Fingerprint Scanner is a highly versatile, all-in-one biometric module favored by makers for its built-in processing power. Unlike simpler sensors, the AS608 handles the "heavy lifting" (image rendering, feature finding, and searching) on its own onboard DSP chip, allowing it to work seamlessly with even low-power microcontrollers like an Arduino Uno.
Key Features
- All-in-One Processing: Integrated optical sensor and high-speed DSP handle enrollment and matching internally.
- Onboard Storage: Can store and manage between 162 to 255 fingerprint templates (depending on the specific firmware version) in its internal flash memory.
- Two-Phase Security: Supports both 1:1 Matching (verifying a specific user) and 1:N Searching (identifying a user from the entire database).
- Visual Feedback: Features a built-in LED (usually green or red) that lights up during the scanning process.
- Flexible Interface: Uses a standard TTL Serial (UART) interface, making it "plug-and-play" with Raspberry Pi, Arduino, ESP32, and PCs.
Best Use Cases
- Biometric Door Locks: Perfect for home automation or safe boxes.
- Attendance Systems: Creating a "clock-in" station for offices or classrooms.
- User Identity for DIY Projects: Restricting access to a Raspberry Pi terminal or an arcade machine

The GY-BMI160 is a highly integrated, low-power 6-axis inertial measurement unit (IMU) designed for precise motion tracking. It combines a 16-bit digital, 3-axis accelerometer and a 3-axis gyroscope into a single compact module, making it an ideal choice for space-constrained and battery-sensitive applications.
At its core lies the Bosch BMI160 sensor, which features advanced internal power management, intelligent interrupt engines, and precise synchronization capabilities, allowing it to deliver high-performance motion sensing with minimal power consumption.
Key Features
Integrated Sensing: Combines a 3-axis accelerometer and a 3-axis gyroscope on a single chip.
Low Power Consumption: Optimized for wearable devices and battery-operated electronics.
High Precision: 16-bit data output with selectable full-scale ranges for both the accelerometer and gyroscope.
Integrated Features: Includes on-chip interrupt engines for motion detection (step detection, tap/double-tap, any-motion, orientation).
Communication Interfaces: Supports both I2C and SPI digital interfaces for easy integration with microcontrollers like Arduino, ESP32, or STM32.
Compact Design: The module form factor is designed for easy breadboarding and integration into prototyping projects.

Using with Raspberry Pi
Using the GY-BMI160 with a Raspberry Pi is a straightforward process, as the module supports the standard I2C communication protocol, which is natively supported by the Raspberry Pi GPIO header.
Wiring Guide
You will need to connect the module to the Raspberry Pi's I2C pins. Ensure you are using the 3.3V pin on the Pi, as the BMI160 is a 3.3V device.
| GY-BMI160 Pin | Raspberry Pi Pin (GPIO Header) |
| VCC | 3.3V (Pin 1) |
| GND | GND (Pin 6 or 9) |
| SCL | SCL (Pin 5) |
| SDA | SDA (Pin 3) |
Step-by-Step Setup
Enable I2C:
Open your terminal on the Raspberry Pi.
Run
sudo raspi-config.Navigate to Interface Options > I2C and select Yes to enable it.
Reboot your Pi:
sudo reboot.
Verify Connection:
Install the I2C tools:
sudo apt-get install i2c-tools.Run the detection command:
i2cdetect -y 1.You should see a device address (typically
0x68or0x69) appear in the grid. This confirms the Pi sees the sensor.
Install Python Libraries:
The most common way to interface with this sensor is using Python. You will need the
smbus2library or a specific BMI160 wrapper.Install smbus:
sudo apt-get install python3-smbus.You can then search for available GitHub repositories for "BMI160 Python Raspberry Pi" to find pre-written drivers that handle the register communication for you.
Reading Data:
Once you have the library installed, you can run a simple test script to read the acceleration and gyroscope values (X, Y, Z axes).
Tip: Remember that the raw data requires scaling based on the range you set (e.g., ±2g, ±250°/s) to convert the values into meaningful units like $m/s^2$ or degrees per second.
Important Considerations
Logic Levels: Always ensure you are using 3.3V for the signal lines. Connecting to 5V pins can damage the sensor or the Raspberry Pi.
Interrupts: If you need to use the advanced features like "step detection," you will need to connect the INT1 or INT2 pins of the module to one of the Raspberry Pi's GPIO input pins and configure an interrupt handler in your code.
Calibration: IMUs often require a calibration routine to remove "bias" or "offset" errors when the device is stationary.

The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted, and that the module is future proof: using Wi-Fi allows a large physical range and direct connection to the internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. ESP32 supports a data rate of up to 150 Mbps, and 22 dBm output power at the antenna to ensure the widest physical range. As such the chip does offer industry-leading specifications and the best performance for electronic integration, range, power consumption, and connectivity. The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that developers can continually upgrade their products even after their release.

3D printing plastics often have low yield strength and cannot reliably produce threaded features. Embedded metal nuts provide stronger and more precise threading for hidden fasteners. The nut melts and reflows the plastic around it, enhancing its strength. However, there are design constraints - the nut must be on a part face and cannot be reinforced beyond the plastic's properties.
