Our high precision Quartz Clock Mechanisms are great if you want to make your own clock or for replacing faulty clock mechanisms and come with all required fixing hardware and hour, minute and second hands.

They are accurate to within 30 seconds per month and run from one AA Battery which lasts over a year. The time is easily set or adjusted with the dial on the back of the unit.

Popular uses include laser cutting custom designs from Perspex or plywood to make into clocks

Features

• Power: 1.5V AA battery (not included)
• Brand new and high quality
• Easy and simple design
• Great for repairing, replacing or making a clock

A key point is that BMP280 is compatible with two digital interfaces, I2C and SPI. This digital barometer has some interesting applications. By measuring the absolute pressure of the environment and converting this into altitude. you will have a reliable sensor for determining the height of your robot, plane or projectile. This sensor is capable of achieving an accuracy of 1m, with noise of only 17cm in ultra-high resolution. The device will operate at only 0.3uA meaning low current draw for battery powered applications.

Specifications

• 1.8V to 3.6V Supply Voltage
• Low power consumption - 0.5uA at 1Hz
• I2C interface
• Max I2C Speed: 3.5 MHz
• Very low noise - up to 0.02hPa (17cm)
• Fully calibrated
• Pressure Range: 300hPa to 1100hPa ( 9000m to -500m)
• Weight: 1.18g
• Size: 21mm x 18mm

What's in the box?

1 x BMP280 Digital Barometric Pressure Sensor Board Module
1 x Male to Male 4 pin header

Using the BMP280 with Raspberry Pi

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.

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:

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.
