3-in-1 Aluminum Heat Sink Set for Raspberry Pi 3
[Aluminium Heat Sink] ❄️ 3-in-1 Aluminum Heat Sink Set for Raspberry Pi 3 High-Quality Aluminum • Self-Adhesive Thermal Tape • Improved Cooling • Easy Installation The 3-in-1 Aluminum Heat Sink Set for Raspberry Pi 3 is a premium cooling accessory designed to improve heat dissipation and maintain stable operating temperatures for Raspberry Pi boards. Manufactured from high-quality aluminum, these heat sinks efficiently transfer heat away from critical components, helping improve performance and extend the life of your Raspberry Pi. The kit includes three aluminum heat sinks of different sizes to cool the processor, Ethernet/LAN controller, and other heat-generating ICs. Each heat sink comes pre-installed with a high-performance thermal adhesive backing, allowing quick and secure installation without the need for additional thermal paste or glue. By reducing operating temperatures, the heat sinks help prevent thermal throttling during continuous operation, making them ideal for overclocking, media centers, home servers, IoT applications, industrial automation, and embedded systems. ⭐ Features Premium-quality aluminum construction Excellent thermal conductivity Self-adhesive thermal tape for easy installation No thermal paste required Lightweight and durable Improves heat dissipation Reduces processor temperature Helps prevent thermal throttling Ideal for continuous operation and overclocking Designed specifically for Raspberry Pi boards Corrosion-resistant aluminum finish Easy peel-and-stick installation 📋 Technical Specifications Product Type: Aluminum Heat Sink Set Compatibility: Raspberry Pi 3 Model A, A+, B, B+ Material: Aluminum Color: Silver Quantity: 3 Heat Sinks Mounting Method: Self-Adhesive Thermal Tape Thermal Interface: Pre-applied Thermal Adhesive Cooling Type: Passive Cooling Weight: Lightweight Installation: Peel-and-Stick 🔧 Applications Suitable for: Raspberry Pi 3 Model B Raspberry Pi 3 Model B+ Raspberry Pi 3 Model A+ Raspberry Pi 3 Model A Raspberry Pi Media Center Home Automation Projects IoT Devices Embedded Systems Robotics Projects Industrial Controllers NAS Servers Retro Gaming Consoles AI Edge Computing Educational Projects DIY Electronics 📦 Package Includes 1 × Large Aluminum Heat Sink (CPU) 1 × Medium Aluminum Heat Sink (LAN/Ethernet Controller) 1 × Small Aluminum Heat Sink (Additional IC / Spare)
Laser Module 650NM 5V
[Laser Module] Voltage: 3.0 V – 5 V. Driver: APC circuit. Line length: about 135 mm. Transmit power: 58mW. Operating Current: 40mA. Operating Current: 40mA. Operating temperature: -36◦C ~ 65◦C. The LASER MODULE 650NM 5V head is composed of a light-emitting tube, condenser lens, and adjustable copper sleeve and it is assembled when delivered, the focal length of the lens is adjusted glued by strong glue stick, which can work directly after connecting to a 5V DC power supply. Laser Diode Module is a breadboard friendly, low cost having the wavelength of 650nm and operating voltage of 5V. The laser head is composed of a light-emitting tube, condenser lens and adjustable copper sleeve and it is assembled when delivered, the focal length of the lens is adjusted glued by strong glue stick, which can work directly after connecting to a 5v dc power supply. Pay attention to the laser cell to prevent from being burnt or battery explosion due to a short circuit when removing the battery. PINOUT 1 – GND 2 – 5V 3 – S (Control: HIGH = Laser on) Applications : Laser test tools. Concentricity positioning. Medical equipment positioning. Production of signal equipment. Use for DIY or robots. All kinds of level meters. Laser projector. Laser toys, etc. Warning!!! This is a low power laser device, however as with all laser devices care should be taken when in use. You should never look directly in to its beam or point the laser at another person. Doing so may cause permanent eye damage. This item is not suitable for children. Package Includes : 1 x LASER MODULE 650NM 5V.
