[Discontinued] SainSmart Mega2560 + SainSmart Prototype Shield V3 +SainSmart 2-Channel Relay+1602 IIC LCD For Arduino

Overview:

SainSmart MEGA 2560 Board for Arduino:

This is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

This SainSmart Prototype Shield V3 processes technology, motherboards, small gold square pad spacing, welding components easier. SOP28 SMD component package to be more handy electronics enthusiasts will not be directly insert bound components.

SainSmart 2-Channel Relay:  This is a 5V 2-Channel Relay interface board, Be able to control various appliances, and other equipments with large current. It can be controlled directly by Micro-controller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) .

5V 2-Channel Relay interface board, and each one needs 15-20mA Driver Current
Equiped with high-current relay, AC250V 10A ; DC30V 10A
Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)   
Indication LED’s for Relay output status

SainSmart 1602 IIC LCD: This is another great blue backlight LCD display. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
