Comimark 1Pcs Xbee/Bluetooth/SRS485 RS485/APC220 I/O Sensor Expansion Shield V5.0 for Arduino - LY404

• UPC   657835686116
• RS485It uses an SP485CN chip to handle comms.The screw terminals (assuming that the three jumpers are set to '485') marked 'A' and 'B' go directly to the IC 'A' and 'B' pins (6 & 7 respectively).The screw terminal marked VCC goes to the IC VCC pin (8), and also to the board's +5V line (i.e. the Arduino's +5V rail).The screw terminal marked GND goes to the IC GND pin (5), and also to the board's GND line (i.e. the Arduino's 0V rail) Our IO expansion board is evolving, this latest V5 IO expansion shield is now supporting Xbee. It combines our popular Xbee shield with IO expansion shield(V4). It even supports SD card which provides the ultimate functional expansion for Arduino so far. As its predecessor, it supports RS485, APC220, Bluetooth communication, servo control. Specification: extensionof 14digitalIOports(12servointerface)and power Digital-portexternalpower supply andan onboardpower supply automaticswitching.
