ULN2803A 8-Channel Darlington Transistor Array Module

The ULN2803A 8-Channel Darlington Transistor Array Module is an excellent solution for driving high-current loads in your electronic projects. The Darlington transistor circuit consists of not just one transistor, but a pair of them connected in a specific way. This connection allows the current amplified by the first transistor to enter the base of the second transistor, where it is re-amplified.
