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.

BME280 is a high-precision, small-volume, low-energy pressure sensor that can be used in mobile devices. Its performance is excellent, the absolute accuracy can be as low as 0.2Pa, and the power consumption is very low, only 2.7uA. The BMP280 uses a powerful 8-pin ceramic leadless chip in a thin carrier (LCC) package, which can be directly connected to various microprocessors through I2C and SPI buses.

Features

• Pressure range: 300~1100hPa (altitude 9000m~-500m) Power supply voltage: 1.71V~3.6V
• LCC8 Package: Lead-Free Ceramic Carrier Package (LCC)
• High precision: 0.06hPa (0.5m) resolution in low power mode, 0.2Pa (1.7cm) resolution in high linear mode temperature output
• 12C interface, SPI interface temperature compensation
• Temperature compensation
• Size: 1.5cmx 1.15cm
• Low power consumption: 2.7uA
• No external clock circuit required

Typical application

• GPS precise navigation (dead reckoning, upper and lower bridge detection, etc.) indoor and outdoor navigation
• Monitoring weather forecast for leisure, sports and health care
• Vertical Speed Indication (Rise/Sink Speed) Fan Power Control

Specifications

• Supply Voltage: 1.8 - 5V DC
  
• Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz)
  

Operational Range:
