Arduino Prototype Shield V.5  has a nice standard 0.1″x0.1″ prototying grid with big pads that comes with  stacking headers and plain header. It is  Compatible with tiny breadboards and there is a reset button and a general use button included in it. You can ues it with  UNO, NG, Diecimila and Duemilanove Arduinos. The power arduino prototype rails down the middle and sides.

Arduino Mega Prototype Shield comes with all hardware included and  can be directly pulg into Arduino MEGA. It this we can use ‘mini’ or medium bearboard . There are lost of GND and +5V rails with a reset button up top. .There  are  Extra 6mm button and DIP prototyping area makes it easy to add more chips.It is compatible with Arduino Mega pinout. It has PCB design.

The Arduino   Gps shield is based on EB-365 GPS module that comes with Micro SD interface. It has got a UART interface and a active antenna design with high receive sensitivity. It has got a extremely fast time to first fix at low signal level. It is compatible with Arduino Uno boards. It is easy to setup.

The Arduino Ethernet Shield R3 allows an Arduino board to connect to the internet. This shield also has a Micro SD card socket, with active voltage translators  and reset switch. To use this shield we should mount it on top of Ardunio bords.It supports up to eight simultaneous socket connections. It can be Power Over Ethernet ready Magnetic Jack. The Arduino Ethernet Shield R3 provides a standard RJ45 ethernet jack.

Esp 12 motor shield is large current motor driven module can compatible with ESP12E Dev Kit and NodeMCU. It is  Dual high-power H-bridge drive with L293DD  chip. The module also has several pins and mostly used for DIY a WI - FI  RC smart car or any type of robotics and many more. It can drive two motors at oncewith a power swtich in-built.

The  USB Host Shield  based on the MAX3421E allows you to connect  a Arduino board to a  USB device . It is   is a USB peripheral/host controller containing the digital logic and analog circuitry.  It works with standard dual 5/3.3V board  and 3.3V-only for  Arduino Pro boards. It has inbuilt reset button and supports HID devices such as keyboard , mouse also Mass storage devices such as USB sticks and many more. It also support android mobile phone . USB HOST mode and USB HUB protocol.

The CNC/Stepper Motor Shield for Arduino is a  shield which uses opensource firmware on arduino to control 4 stepper motors using 4 pieces of A4988 Stepper Motor driver
breakout board. It can be applicable in various fields like :- Robotics,  linear motion project, CNC routers, laser cutters and many more.

The LCD Key shield used 16 by 2 LCD display.  It is developed for arduino compatible boards. There are 5 keys and 1 reset button. The keys are used for up, down right, left and select. The backlight is adjusted with integrated the potentiometer. It use 4 bit Arduino lcd library. It can be used as display unit.

The  SD Shield is compatible with 3.3V and 5V arduino mainboards. It is a break out board for standard SD and TF card that adds storage to arduino projects. It use only the SPI ports of arduino. It is stackable as well. This shield has pwe indicator and 4 pn grove electronic brick interface.

The monster motor driver shield is capable of driving a pair of high-current motors as in this motor the L298H-bridge is replaced with a pair of VNH2SP30 full bridge motors. It has the feature of under voltage and over voltage shutdown alos current sensing available analog pin. It is capable of driving a high current motors.
