Description:
The timing belt originally comes from the automotive sector. Later developments of belt shapes resulted from the use of timing belts in scanners. Today, the 3D printer sector is able to benefit particularly from these developments. Toothed belt drives are a very common drive element for positioning in the 3D printer industry due to their high positioning accuracy and the small installation space required. Additional advantages include their low maintenance requirements and long service life.

Premium Passive Cooling Case for Raspberry Pi 5 – Matte Black Aluminium
Upgrade your Raspberry Pi 5 setup with the ultimate blend of silent performance and rugged protection. Designed specifically for the high-power requirements of the Pi 5, this Black Anodised Aluminium Case transforms the entire enclosure into a massive, efficient heatsink.
Forget about fan noise or mechanical failure. This passive cooling solution uses precision-engineered internal thermal columns to pull heat directly away from the CPU, RAM, and Power Management IC (PMIC), ensuring your Pi 5 stays cool even under heavy computational loads.
Why Choose Passive Cooling?
- 100% Silent Operation: Ideal for home media centres (Kodi/LibreELEC), recording studios, or bedroom labs where fan whirring is a distraction.
- Zero Maintenance: With no moving parts, there’s no fan to clog with dust or fail over time—perfect for remote IoT deployments or industrial "set-and-forget" projects.
- Superior Durability: The sandblasted aluminium alloy provides a "tank-like" shell that protects your board against drops, static, and everyday wear and tear.
Key Features
- Precision CNC Cutouts: Provides unhindered access to all dual micro-HDMI ports, USB 3.0/2.0 ports, Ethernet, and the new PCIe FPC connector.
- Integrated Power Button: Includes a tactile extension so you can use the Pi 5’s new onboard power button without opening the case.
- Warning: Case might interfere with Wi-Fi and Bluetooth signals.
Technical Specifications
- Material: High-grade Anodised Aluminium Alloy
- Colour: Matte Black
- Cooling Type: Passive (Conductive Thermal Heat Dissipation)
- Compatibility: Raspberry Pi 5 all variants
- Dimensions: ~91mm x 64mm x 32mm
What's in the box?
1 x Top & Bottom Aluminium Shells
1 x High-Conductivity Thermal Pad Set (Pre-sized for Pi 5 components)
1 x Bolt pack
1 x Allen Key for quick assembly
Pro Tip for PiShop Customers: Passive cooling is excellent for standard desktop use and media streaming. However, if you plan on heavy 24/7 video encoding or extreme overclocking, consider our Active Cooler for maximum thermal headroom.

The LD2410C is a high-sensitivity 24GHz millimeter-wave (mmWave) radar module designed for advanced human presence detection. Unlike traditional PIR sensors that only detect movement, this FMCW (Frequency-Modulated Continuous Wave) radar can sense the tiny chest movements of a stationary person (breathing), making it the ultimate solution for "smart room" occupancy.
Why choose mmWave over PIR?
- Stationary Presence: Detects sitting, standing, and even lying down. Your lights will never turn off while you're reading or watching TV again.
- Environmental Immunity: Not affected by temperature, light, smoke, or humidity.
- Invisible Installation: The radar can penetrate plastic shells and glass, allowing it to be hidden inside a project box or behind a thin wall for a clean aesthetic.
Key Features
- Long-Range Sensing: High-precision detection up to 5–6 meters.
- Wide Coverage: Broad ±60° detection angle ensures full room coverage.
- Smart Tuning (Bluetooth & Serial): Easily configure "Gate" sensitivity, distance zones, and delay times via the HLKRadarTool App (iOS/Android) or a serial debugging tool.
- Fine-Grained Zones: Divide the sensing range into intervals and shield interference from objects outside the target area (e.g., a fan or a window).
- Compact Design: Ultra-small footprint (16mm x 22mm) for easy integration.
- Wide Voltage Support: Reliable performance with a 5V to 12V power supply.
Technical Specifications
- Operating Frequency: 24GHz (ISM Band)
- Detection Type: Motion, Micro-motion (Breathing), and Stationary Presence
- Voltage: 5V – 12V (Average current ~80mA)
- Output: High/Low GPIO (3.3V Logic) and UART Serial (256,000 baud)
- Mounting: Supports Ceiling or Wall mounting
- Regulations: FCC and CE compliant
Ideal Applications
Smart Lighting: Energy-saving control for homes and offices.
AIoT Wake-up: Automatically wake up advertising screens or tablets when a person approaches.
Safety & Security: Detect intruders or prevent UV lamps from turning on while people are present.
Smart Appliances: Power down TVs or Aircons when a room is truly unoccupied.

1 x LD2410C Human Presence Sensor Module (Bluetooth Enabled)
Resources
Pro-Tip for Home Assistant Users: This module is fully compatible with ESPHome. By connecting the TX/RX pins to an ESP32, you can bring real-time distance and occupancy data directly into your dashboard with no complex coding required.
To use the LD2410C with a Raspberry Pi (like the Pi 4 or Pi 5), you have two main ways to set it up: a Simple Digital method (Quick & Easy) or a UART Serial method (Advanced Data).
1. The Hardware Hookup (Wiring)
The LD2410C has 5 pins. You only need 3 of them for basic operation.
| LD2410C Pin | Raspberry Pi Pin | Description |
| VCC | Pin 2 or 4 (5V) | Power (Supports 5V - 12V) |
| GND | Pin 6 (GND) | Ground |
| OUT | Pin 7 (GPIO 4) | Digital Output (High when presence detected) |
| TX | Pin 10 (GPIO 15 / RXD) | UART Transmit (For advanced data) |
| RX | Pin 8 (GPIO 14 / TXD) | UART Receive (For advanced data) |
Method A: Simple Digital Setup (The Easiest Way)
The OUT pin on the sensor behaves like a traditional PIR sensor. It goes HIGH (3.3V) when it detects a person and LOW when the room is empty.
Python Code (Digital):
from gpiozero import DigitalInputDevice
from signal import pause
# LD2410C OUT pin connected to GPIO 4
sensor = DigitalInputDevice(4)
def person_detected():
print("Presence Detected! (Stationary or Moving)")
def room_empty():
print("Room is now empty.")
sensor.when_activated = person_detected
sensor.when_deactivated = room_empty
pause()Method B: UART Serial Setup (For Distance & Zones)
If you want to know how far away the person is or differentiate between "moving" and "stationary" targets, you must use the UART pins.
1. Enable Serial on your Pi:
- Run
sudo raspi-config. - Go to Interface Options > Serial Port.
- Select No for "login shell" and Yes for "serial port hardware".
- Reboot.
2. Python Library:
The easiest way to handle the complex radar data is using the aio-ld2410 library.
pip install aio-ld24103. Python Code (UART):
import asyncio
from aio_ld2410 import LD2410
async def main():
# /dev/ttyAMA0 is the default hardware serial port on Pi
async with LD2410('/dev/ttyAMA0') as device:
print("Connected to LD2410C")
async for report in device.get_reports():
print(f"Target: {report.target_state}")
print(f"Moving Distance: {report.moving_target_distance}cm")
print(f"Static Distance: {report.static_target_distance}cm")
asyncio.run(main())Important Tips for Raspberry Pi Users:
- Power: While the Pi can power the module from its 5V pins, the LD2410C can draw up to 80-100mA. Ensure your Pi power supply is reliable (especially on the Pi 5).
- Bluetooth Conflicts: The LD2410C has Bluetooth. You can use the HLKRadarTool app on your phone to calibrate the sensor while it is still connected to the Pi. This is the best way to set your sensitivity "Gates" without writing a single line of config code.
- Logic Levels: The LD2410C uses 3.3V Logic for its TX/RX and OUT pins, which is perfectly safe for the Raspberry Pi's GPIO pins.
