The Banana Pi M2 Zero is an ultra compact single board computer which measures only 65mm*30mm. Its external interfaces are the same as the Raspberry Pi Zero W, and it will fit almost all cases and accessories for the Zero W. It uses the quad-core Cortex A7 Allwinner H3/H2+processor, with 512MB RAM. It’s ideal for light-weight systems and space-limited applications. Like other members of the Banana Pi family, it supports both Linux and Android operating systems.

A barcode reader, also called a price scanner or point-of-sale ( POS ) scanner, is a hand-held or stationary input device used to capture and read information contained in a bar code . A barcode reader consists of a scanner , a decoder (either built-in or external), and a cable used to connect the reader with a computer.

A battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode.The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term “battery” specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.
Primary (single-use or “disposable”) batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used for flashlights and a multitude of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an applied electric current; the original composition of the electrodes can be restored by reverse current. Examples include the lead–acid batteries used in vehicles and lithium-ion batteries used for portable electronics such as laptops and mobile phones.
Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to, at the largest extreme, huge battery banks the size of rooms that provide standby or emergency power for telephone exchanges and computer data centers. Batteries have much lower specific energy (energy per unit mass) than common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in converting electrical energy to mechanical work, compared to combustion engines.
Rechargeable batteries (also known as secondary cells) are batteries that potentially consist of reversible cell reactions that allow them to recharge, or regain their cell potential, through the work done by passing currents of electricity.

Barometric Pressure sensor measures the absolute pressure of the air around it. This pressure varies with both the air and altitude. Depending upon the interpretation of the data, changes in the weather can be monitored, altitude can be measured, and any task can be done that requires the accurate pressure measurement.

Single row of 40-holes, female header with swiss round machined pins. These units have very high quality round pins to accept and retain machine pin headers much better. Can be cut to size with a pair of wire-cutters. Standard .1″ spacing. We use them extensively in the Olimex development boards. They mate very well with break away headers.

A pin header (or simply header) is a form of electrical connector. It consists of one or more rows of male pins typically spaced 2.54 millimetres (0.1 in) apart, but sometimes 2 millimetres (0.079 in) or 1.27 millimetres (0.05 in) is used as well. The distance between pins is commonly referred as pitch in the electronic community.

- Hole distance: 16MM
- Aperture: 2.5MM
- Voltage range: 2.4-5V
- Maximum output current: 500MA
- PCB size: L23MM *W20MMThe lamp brightness can be adjusted by requirement, it is very to operate.
It can touch in medium protection, such glass, acrylic, plastic, ceramics and so on, which is very safe.
Wide application of voltage range, you can choose arbitrarily between 2.4V to 4.5V.
Simple applied circuit, less peripheral devices, easy processing, low cost.
Anti power and phone interference, the EFT can reach above +/-2KV; the touch response sensitivity and reliability will not affected by the close distance or multi-angle mobile phone interference.
Install: Neednrsquo;t to touch copper foil directly,the dimming can be processed across the acrylic glass(above 3mm) or plastic.
Application: It can control LED module, light and so on.It is available for indoor LED, lighting lamp,DIY automotive lights dimming refit.
Function:Single touch,using the principle of capacitance touch.The default function is switch, dimming, with brightness memories LED touch dimming.It will light slowly when turn on the lights, and become dark slowly when turn off, which effectively avoid the stimulation to eyes.
Dimming mode: Non-polar PWM dimming.
Wiring method: PCB board(VCC,GND) is power input,(LED+, LED-) is connected with the LED lamps of positive and negative level (fingerprint) touch area.

This is Carbon Monoxide sensor is suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 20 to 2000ppm.This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

Conductive ink pen helps you to come out with the stroke of a circuit diagram that can conduct electricity, so that if everything will become more wonderful and funny, as you have already been tired of the traditional way about drawing a circuit diagram and want to try some new things. It uses autonomic modulation paint named Buddy, the main ingredient is silver conductive copper mixed powder and nickel powder, it can conduct electricity in two or three minutes after air-dried. With its superior performance, you can do more simple or complex electronic production.
- Note: Shake well before using and you need to maintain a continuous and uniform line when you write, if still not conducting, you’d better to check and find the break by using the multi-meter.
