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.

Hot Question:
1) Where can i download the software?
Answer: You can download the software via this link:http://www.nsccn.com/download/soft/nfc/nfcPro_wbw.exe
2) Which chip inside in the 5pcs blue keyfobs and 5pcs white cards?
Answer: If you buy the RFID copier + 5pcs UID keyfobs + 5pcs T5577 cards. The 5pcs UID keyfobs is working with 13.56MHz frequency, used to copy the MF 1k card. The 5pcs T5577 cards is working with 125KHz frequency, used to copy the EM4100, TK4100 cards. They are different type card.
3) Why the 5pcs cards in the package read failure?
Answer: Please don't worry, these 5pcs white cards is T5577 (EM4305) type, they haven no data before write. They will can be read successfully after finished written from your TK4100 or EM4100 type card. Thank you.

Product size: 35.5 * 17 * 8.3 mm
Input voltage range: 6 to 26 v
Output voltage: 5.2 V (consider charging line loss, output is about 5.2 V, the load end is around 5 V)
Limit the output current: 3 a (in the absence of radiator, stable output current limit is 2 a)
Note 1: is the cathode can't meet the, and the input voltage can't more than 26 v, otherwise it will result in the chip damage!
Note 2: in current work, not touch on the circuit board sampling resistor, IC, or may result in output voltage mutation damage equipment!

These are suitable for DIY projects and the Raspberry Pi pcb as the screw outside diameter is only 2.5mm that fits in the Pi mounting holes.
Brass 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: Brass 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: Brass 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, brass standoffs can help dampen vibrations transmitted to the PCB, thereby reducing the risk of component failure or solder joint fatigue over time.
Grounding: Depending on the design, brass standoffs can also be used as grounding points for the PCB. By connecting the standoffs to the ground plane on the PCB, they provide a convenient and reliable grounding solution.
Overall, brass 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.

This is a small board with a load switch that allows a Raspberry Pi to automatically temperature control a fan (not included) via GPIO3.
It's an affordable, compact and light way to add smart temperature control to your own Raspberry Pi enclosure or project, and can be used to toggle power for other devices using up to 1A as well.
Compatible with:
What's in the box?
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
