The Arduino Compatible USB Host Shield is based on the MAX3421E, which is a USB peripheral/host controller containing the digital logic and analog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0. it is compatible with more Arduinos – not only UNO and Duemilanove but also Mega and Mega 2560 work with a Standard variant of this shield out of the box. No more SPI re-wiring and code modifications – just solder included stackable connectors (2×3 ICSP connector’s female side should be facing down), plug and play! Using Arduino Compatible USB HOST function, let your Arduino communicate with other USB devices, and supports USB HUB function.USB Host shield adds USB Host capabilities to the Arduino board.

The latest Arduino Controller Sensor Shield V5.0 is producted by ALSRobot. This Sensor Shield expansion board to retains the advantages of version V4.0 on the basis of stack design, PCB Immersion Gold processing technology.newly added many kind of interface,for example,IIC interface、32 channels servo motor interface、bluetooth communication module interface、SD Card communication module interface and so on,more convenient. Sensor Shield allows you to connect to various modules like sensors, servos, relays, buttons, potentiometersEach functional module has buckled port with VCC, GND and Output, which has corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking.
