This Board uses IRF520 MOSFET as the controlled device. For easy hook-up to microcontroller, three separate pins are provided for VCC, GND and IO. It can be used to control upto 24v with 5A DC load. Make sure to use an additional heatsink with the MOSFET. It also has Screw terminals to easily connect the high loads that use a bigger diameter of wires. An LED indicator provides a visual indication of when your load is being switched.

SPECIFICATIONS

This DC 3-6 V Mini Micro Submersible Water Pump is a low-cost, small-size Submersible Pump Motor that can be operated from a 2.5 ~ 6V power supply. It can take up to 120 liters per hour with a very low current consumption of 220mA. Just connect the tube pipe to the motor outlet, submerge it in water, and power it.

Note:

1. Make sure that the water level is always higher than the motor. The dry run may damage the motor due to heating and it will also produce noise.
2. This product is available in two different colors like Black and White, which will be shipped randomly so please note you will get anyone out of both colors.

Features :

1. DC 3v to 6v submersible pump
2. Micro mini submersible water pump 3v to 6v
3. DC water pump for DIY
4. DC pump for HOBBY kit.

Package Includes :

1 x DC 3-6 V Mini Micro Submersible Water Pump

Though it’s an industrial module, this LCD display is extremely easy to use. The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended as a cell phone screen.

This Nokia 5110 LCD Display Module is mounted on an easy-to-solder PCB. The Nokia 5110 LCD Module uses a Philips PCD8544 LCD driver, which is designed for mobile phones.

Nokia 5110 LCD Display Module is a low-cost monochrome LCD module comprised of 84 X 48 pixels that can be used to display rich graphics and text content. This module is a revision that accepts 3-5V input. So no extra level shifter is needed.

Interfacing with UNO Board:

It uses the PCD8544 controller, which is the same one used in the Nokia 3310 LCD. The PCD8544 is a low-power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCD8544 interfaces to microcontrollers through a serial bus interface.

Pin Configuration :

1. RST– reset
2. CE– chip selection
3. DC– data/commands choice
4. DIN– serial data line
5. CLK– serial Clock Speed.
6. VCC– 3.3V
7. LIGHT– backlight control terminal
8. GND– power negative

Operation of Nokia 5110 LCD Display Module at 3.3V 

Many devices that can be used with an Arduino, require a power supply of 3.3V. This is also the case with the Nokia 5110. The best way to deal with 3.3V devices is to take an Arduino Pro, which can run on 3.3V.

Thanks to the internal clamp of the PCD8544 we can use a very simple level shifter. Four current limiting resistors of 10kΩ can do the job. When an LCD control line is high, the current through the 10kΩ resistor is just 40uA, so this is harmless. Note that we can’t read back from the LCD with this circuit.

Operation of Nokia 5110 LCD Display Module at 5V

Because VDD max = 7V, the PCD8544 controller can handle 5V, but the Nokia 5110 LCD works best at 3.3V. The four resistors of 10kΩ avoid streaks on the LCD display. (at 5V the screen becomes somewhat black when tested)

Features :

1. 84 X 48 dot matrix LCD, can show 4 lines of characters.
2. Use serial interface communicate with the master processor, the number of interface signal lines reduced greatly, only 8 signal lines including power and GND.
3. Support different types of MCU, such as the Arduino, AVR, SPI, MCS51, and so on.
4. Transfer rate up to 4Mbps, can full speed write display data without waiting time.
5. Can use the conductive glue to connect the module to the printed board, without cables. The metal hooks on the module can fix the module on the printed board, which is very easy to install and replace.
6. LCD controller/driver chip has been bound to LCD chip, the volume of LCD is small.
7. Low power supply, the working current in a normal situation is lower than 200µA and has the power-down mode.
8. “LIGHT” linked with GND, the backlight to be lit.
9. Need you to compress the screen and PCB tighter, might be got loose after the delivery.
10. Use a 3.3V controller, otherwise, the display could be quite vague.

It has a 12-bit resolution providing temperature readings from 0°C to 1024°C (max temperature of the supplied sensor is 450°C) with a resolution of 0.25°C.

Screw terminals allow for connection to the thermocouples spade connectors and a 5 pin standard 0.1″ header provides an interface to a microcontroller such as an Arduino development board.

It is widely used in various auto-sensing of electrical equipment, especially battery-powered automatic control products.

Applications:

1. Low-power consumption
2. Output level: High 3.3V / Low 0V
3. Trigger: repeatable trigger (default)
4. Automatic induction: to enter the sensing range of the output is high, people leave the sensor range automatically delay off high, output low. Ultra-small size.
5. Repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will remain high until people leave after the high variable delay Low (automatically extended sensor module detects the human body after every activity a delay period, and the last time an event is the starting point of the delay time).
6. Wide operating voltage range: the default operating voltage DC4.5V-20V.
7. Micropower: quiescent current <50 microamps, especially for battery-powered automatic control products.
8. Output high signal: easy docking and all kinds of circuits.
