PCB spacers are often used to achieve precise spacing between components. Spacers are shaft, tube, pipe and part fittings that aid in positioning, connection and guiding. A basic spacer is a hollow, round cylinder with a fixed length and inner and outer diameters. Clearance spacers are cylindrical spacers that are not threaded. Specification Material Nylon…
his is an HW-689 PCF8563 Real-time Clock RTC module. It has a variety of functions, including an external programmable clock output, an alarm, a timer, features, external quartz, and a backup battery. The PCF8563 RTC Board provides a real-time clock function that is powered by an onboard battery and operates independently even when the MCU is turned off. I2C real-time clock (RTC) is less expensive and more precise than the DS1302 or DS1307. Features High Accuracy Low Power Consumption Can be interfaced with Arduino Low Cost I2C Real Time Clock (RTC) Pinout: Pin-1: INT…
The PCF8574 I/O Extension Board is used as a remote 8-bit I/O expander for I2C-bus. Up to 8x PCF8574, IO Expansion Board can be connected to the I2C-bus, providing up to 64 I/O ports. It has an I2C pin header on one side and an I2C connector on the other. As a result, connecting the board…
A non-contact voltage tester, also known as a voltage detector, is an electrical tester that aids in the detection of voltage. When troubleshooting or working on a failed asset, voltage presence is useful information to have. A non-contact voltage detector is the first tool you’ll reach for. Non-contact voltage testers operate by sensing a very…
A brushless DC fan uses brushless DC motors (BLDC motors) that have a cross-pattern arrangement of four permanent magnets mounted on the sides of the rotor. Unlike brushed DC motors, BLDC motors do not require any commutator or brushes to operate. The brushless DC fan is made of a combination of a powerful BLDC motor,…
Cable glands allow you to put a cable into a pre-drilled hole. Electrical engineers frequently utilise cable glands in machinery control boxes, distribution panels, electrical appliances, and other devices because they are simple and easy to use. Each gland has an IP68 rating, ensuring its waterproof capabilities and resistance against other environmental conditions. The clamping…
This pH sensor is commonly used to test the pH of a liquid as it measures the hydrogen-ion activity in water-based solutions. Wherever acidity and alkalinity testing is required, it is frequently employed in the chemical businesses, pharmaceutical industry, dye industry, and scientific research. This kit’s drive board works with both 9V systems. It’s also very…
The Phillips head screwdriver was created and patented by Henry Phillips in the 1930s and was originally used on the 1936 Cadillac. The great thing about it is that unlike the flat head screw (with a single ridge at its tip to slide into a screw with one slot), the Phillips screwdriver is self-centering. Its…
