1 x Fan Controller
Resources
How to use
The Fan controller should be connected to the first 6 pins on the header where it uses 5V, GND and GPIO 3 (see images).
To automatically cool your Raspberry Pi when it starts to warm up, add the following to your /boot/config.txt and restart the Pi. You can change the value to make the fan turn on at different temperatures too:
dtoverlay=gpio-fan,gpiopin=3,temp=80000
Note: Raspberry Pi and Fan not included

These are suitable for DIY projects and the Raspberry Pi pcb as the outside diameter is only 2.5mm that fits in the Pi mounting holes.
Nylon standoffs are essential components in electronic projects, particularly in applications where circuit boards need to be securely mounted within an enclosure or chassis.
Here's how they are typically used:
Board Mounting: Nylon standoffs are used to elevate and secure printed circuit boards (PCBs) within an electronic enclosure or chassis. They provide a stable platform for the PCB, preventing it from coming into contact with conductive surfaces that could cause short circuits.
Mechanical Support: Standoffs act as spacers between the PCB and the mounting surface, ensuring proper ventilation and preventing heat buildup. This is crucial for maintaining the integrity of sensitive electronic components.
Isolation: Nylon standoffs help to electrically isolate the PCB from the chassis or enclosure. This isolation is essential for preventing electrical interference, reducing the risk of noise and signal degradation, and enhancing overall circuit performance.
Easy Access: Standoffs facilitate easy access to the PCB for maintenance, repairs, or upgrades. By raising the board above the mounting surface, technicians can easily reach components and make necessary adjustments without disassembling the entire system.
Vibration Dampening: In applications where vibration is a concern, nylon standoffs can help dampen vibrations transmitted to the PCB, thereby reducing the risk of component failure or solder joint fatigue over time.
Overall, nylon standoffs play a crucial role in ensuring the structural integrity, electrical isolation, and proper functioning of electronic systems. Their versatility and reliability make them indispensable components in a wide range of electronic projects.

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

This waterproof ultrasonic distance sensor is for those applications that are a bit more rugged! 25cm - 200cm sensing range.
We have used the SRF05, SRF02 Ultrasonic Distance Sensor many times and for many good reasons. It is pretty easy to use, it performs well, and it is very inexpensive. For collision avoidance robots or intruder detection, this sensor is usually all you’ll need.
However, using the module outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.
For these circumstances you can use this sensor, in more weathered states, even outdoors.

Sensor Usage
Basic working principle
(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz pulse, automatic detecting whether a signal returns;
(3) on signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
