ULN2003 Motor Driver Board

The ULN2003A contains eight Darlington transistors with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600 mA (500 mA continuous) and can withstand at least 50 V in the OFF state. Outputs may be paralleled for higher current capability.The ULN2003A has a 2.7 kΩ input resistor for 5 V TTL and CMOS
