To calculate the total current sourced by the digital outputs use the
following equation:
Where j is the number of digital outputs being used to source current.
Power available at I/O connectors......... 4.50 to 5.25 VDC at 1 A total,
250m A per I/O connector pin
1 Does not include current drawn form the +5 V line on the I/O connectors.
2 Does not include current sourced by the digital outputs.
