A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.Carbon film resistors are a fixed form type resistor. They are constructed out of a ceramic carrier with a thin pure carbon film around it, that functions as restive material.Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. In electronic circuits, resistors are used to limit current flow, to adjust signal levels bias active elements, and terminate transmission lines among other uses.

There are 2 USB ports on the adapter, one is the data transmission port, and the other is the auxiliary power supply port. Usually only the data transmission port is used. If the power supply of the USB port of the computer is insufficient, connect the auxiliary power supply port to strengthen the power supply.


This module is different from the LM2596 and XL4005 buck modules on the market. The chip design power used by them is 15W and 50W.

The upgraded chip has both input and output voltage range, output power and efficiency.

To be better than similar products, the power can reach 75W, with a very high cost performance.

RC522 IC Brief Introduction :

MF RC522 is used in highly integrated 13.56MHz contactless communication card chip to read and write, of NXP for “three” and the application launched a low voltage, low cost, small size, non-contact card chip to read and write, intelligent instruments and portable handheld devices developed better.

The MF RC522 use of advanced modulation and demodulation concept completely integrated in the 13.56MHz all kinds of passive contactless communication methods and protocols. 14443A compatible transponder signal. The digital part handles the the ISO14443A frames and error detection. In addition, support Quick CRYPTO1 encryption algorithm, the term verification MIFARE series. MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transfer rates up to 424kbit / s.

As 13.56MHz highly integrated card reader series chip new family, the MF RC522 MF RC500 MF RC530 there are many similarities, but also have many of the characteristics and differences. Communication between it and the host SPI mode, helps to reduce the connection, reduce PCB board volume and reduce costs.

High Quality HC--SR501 PIR Infrared Sensor Module.

PIR sensors, often referred to as, "Passive Infrared" or "IR motion" sensors, enable you to sense motion.

Everything emits a small amount of infrared radiation (IR), and the hotter something is, the more radiation it emits.

PIR sensors are able to detect a change in average IR levels of their detection zone (e.g. when a human enters a room, that room will increase in temperature slightly) and hence sense motion.

This one's great, as it can be powered via the Raspberry Pi's 5V output, and be read directly from the Raspberry Pi's GPIO input (as the sensor has a digital 3.3V output!)

This PIR includes an adjustable delay before firing (approx 0.5 - 200 seconds), has adjustable sensitivity and two M2 mounting holes.

 It runs on 4.5V-20V power (or 3V by bypassing the regulator with a bit of soldering) and has a digital signal output (3.3V) high, 0V low.

Its sensing range is up to 7 meters in a 100 degree cone.
