8CH USB Logic Analyzer This is a very affordable 24Mhz 8-channel USB Logic analyzer. This is a hobbyist level analyzer, ideal for testing your Arduino or other hobbyist microcontroller’s communications. A logic analyzer is a must-have tool for any serious electronics hobbyist. With a logic analyzer, it is possible to see a visual representation of the zeros and ones that are flashing between two components. A logic analyzer is different from an oscilloscope because the analyzer allows you to capture the data on a PC for a more detailed analysis of the data that is being transmitted and received. This logic analyzer supports 10 different communications standards (see Specifications below). with 8 channels, it will allow you to monitor up to 8 different wires. So on an Arduino, you could monitor the Serial port (tx/Rx pins), the I2C port (pins A4, A5), and the SPI port (pins 10, 11, 12, and 13) all at the same time. If you do single-chip development, ARM system development or FPGA development then we strongly recommend you buy this product. To do a good job, one must first sharpen their device MCU-related products, as long as you do this tool will be your crescent moon nod. Especially do UART, SPI, and IIC communication debugging, which absolutely lets you get twice the result with half the effort. Read more: What is a Logic Analyzer

8MHz Crystal Oscillator - (Pack of 5) The 8 MHz crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. It provides clock pulses of 8 MHz frequency. The popularity of the crystals is due to the low cost. How are crystal oscillators useful? One of the most important traits of the crystal oscillator is that it exhibits very low phase noise. In the crystal oscillator, the crystal mostly vibrates in one axis, therefore only one phase is dominant. This property of low phase noise makes them particularly useful in telecommunications where stable signals are needed, and in scientific equipment where very precise time references are needed. The result is that a quartz crystal behaves like a circuit composed of an inductor, capacitor and resistor, with a precise resonant frequency. Also check pack of 10, 16MHz Crystal Oscillators offered by Iotcart. The crystal oscillator is used to provide clock pulses of 8 MHz frequency and can be utilized as a UART clock at 6×1.8432 MHz. It allows integer division to common baud rates and serves as a common clock for AVR microcontrollers.
