The MikroDrive Board is an add-on board that employs a high-voltage, high-current ULN2803AN Darlington transistor array. This array of 8 NPN Darlington transistors allows interfacing between a low-level logic circuitry and multiple peripheral power loads. The ULN2803A IC allows digital outputs capable of providing current of only up to several milliamperes to be connected to devices that require driving current of up to several hundreds of milliamperes. The MikroDrive Board provides power loads up to 260W (350 mA x 8, 95V). The transistors are of.
