Arduino I/O Shield

• Six relay outputs with a maximum current of 0.5A and a maximum voltage of 30V
• One ampere maximum load per output and 30V maximum per output
• Stackable design, allowing the shield to be used with other shields
• Requires one Arduino UNO (not included)
• Uses pins 8 to 13 as outputs, pins A0 to A5 as analog inputs, and pins 2 to 7 as digital inputs

The Arduino I/O Shield is a general-purpose input-output shield. It is also available as a kit version, KA05.
