3 / 8 page ![]() Digital 10 NC4 is disconnected with COM4 NC4 is connected with COM4 NO4 is connected with COM4 NO4 is disconnected with COM4 Note: NC: Normally Closed; NO: Normally Open. More detalis: PROG SWITCH: o PROG: When programming or download the code if you plug the Xbee/bluetooth on the module o RGN: Run the module after finishing downloading the code S1,S2,S3,S4: 4 Buttons to test the module that you needn't program,S1‐ S4 correspond to relay1‐ relay4 Servo Power Supply: Just can supply power to the digital IO pins. 4 Digital IO selection headers for the Relays: o D2,D7,D8,D10: Default,connect to Arduino digital 2,7,8,10 to drive the relays o IO0,IO1,IO2,IO3:Connect to XBee's IO pins o You can connect the middle pin header after you unplug the jumper, to Arduino digital IO with jumper cables depend on your needed pin mapping to drive relays. For example, when you use the board with an Arduino Ethernet board. They will conflict the digital 10, so you should remove the jumper on D10, and connect the middle pin to other digital IO. XBee interface: The XBee module supports Xbee radios, Bluetooth Bee, and the Wireless programming module. This gives the project a versatile wireless communications capability. |
