Relay Module for Arduino Raspberry Pi, 4 Channels
The Relay Module provides a solution for controlling high current devices that cannot be controlled by the Arduino’s Digital I/O pins due to their current and voltage limits.
The Relay Module features four high quality relays and provides NO/NC interfaces, four dynamic LED indicators to show the on/off state of each relay, and the standardized shield form factor to provide a smooth connection to the Arduino/Seeeduino board or other Arduino compatible boards.
Ethernet Shield for Arduino, Hanrun HR911105A
The Arduino Ethernet Shield allows an Arduino board to connect to the internet.
It is based on the Wiznet W5100ethernet chip (datasheet). The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. You can use the Ethernet library to write sketches which connect to the internet using the shield. The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top.
Atmel Xplained Mini Evaluation Kit with USB Cable
The ATmega328P Xplained Mini evaluation kit is a hardware platform for evaluating the ATmega328P microcontroller.
The evaluation kit comes with a fully integrated debugger that provides seamless integration with Atmel Studio. The kit provides access to the features of the ATmega328P enabling easy integration of the device in a custom design.
Arduino Due with USB Cable
Graphics LCD 128×64 Pixels, QY-12864BG
This is a framed graphical LCD 64×128 with LED backlight. This unit is a very clear STN type LCD with a simple command interface. This new module includes the negative voltage circuitry on board!
Utilizes the extremely common KS0108B parallel interface chipset (datasheet). Interface code is freely available. Includes LED Backlight.
