Module feature and performance: 5A high-power and high efficiency reduction voltage and low ripple High quality and good performance With power light and voltage display with self-correcting. Adopting advanced voltage microprocessor, and the voltmeter error ±0.1V, measuring range is 0~40V (Note: Please make sure input voltage more than 3.5V to make the voltmeter normal working) Touch the button to change input or output voltage, LED indicator light display is measuring voltage, and can autosave which one voltage, keep pressing the key can turn off the voltmeter Input voltage 4.0~38V (the input voltage must be higher 1.5V than output voltage) Adjustable output voltage range: 1.25V~36V (the input voltage must be higher 1.5V than output voltage) Output power can reach 75W. Output current can reach 5A, suggested use it less than 4.5A (note: Please add a cooling fin into power chip, if you use it with high-power)

Pulse sensor is used to test heart rate sensors. Students, artists, athletes, creators, games or mobile terminal developers can develop heart-related and interactive works. Sensor can be worn on the finger or earlobe, It also has an open-source app program, you can put your real-time heart rate displayed by the graph. In essence, a heart rate sensor integrated optical amplifier and noise elimination circuit.

This is the XBee XB24-Z7WIT-004 module from Digi. Series 2 improves on the power output and data protocol. Series 2 modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported. These are essentially the same hardware as the older Series 2.5, but have updated firmware. They will work with Series 2.5 modules if you update the firmware through X-CTU.
