# Title: mikroDrive Board


## Description: IC/Module: ULN2803A Darlington Transistor Array The ULN2803A is a high-current 8x Darlington transistor array that is capable of powering loads up to 260W in total. The open-collector output transistors have integral clamp diodes that protect them against high voltage of self-induction.With a collector-current rating of 500 mA, each Darlington pair may be connected in parallel for higher current capability. It features a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices. Jumper Settings The mikroDrive Board features a Jumper J1 that allows the user to select the power supply source for the ULN2803As output drivers. When J1 is set in Vcc position, the power comes through the IDC10 connector from the 5V microcontroller host system. When the jumper is set to the Vcc-Ext position, the outputs are powered from an external source up to 50V via screw terminals. Applications The mikroDrive Board serves as an ideal choice for designs where power source conversion between low-level logic circuitry and multiple peripheral power loads. Typical power loads include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. Specifications Type Miscellaneous Applications Compact and inexpensive, this board is perfect for use when the power source conversion is needed for your embedded project On-board modules Darlington arrays ULN2803AN, Screw terminals Key Features Output voltage selection jumper on board Interface GPIO Compatibility IDC10 Input Voltage 9-32V DC or 7-23 AC (via external source)
