Details

The ULN2803 output Board allows higher voltage and current devices to be interfaced to the low level logic. Ideally suited for interfacing between low logic level digital circuitry (such as microcontrollers) and the higher current/voltage requirements of lamps, relays, printer hammers or other similar loads for a broad range of computer, industrial, and consumer applications. In built free wheeling clamp diodes for transient suppression. Can drive two unipolar stepper motors.  

• 1 x ULN2803 High Voltage / High Current Transistor Array
• Status LED for each channel
• Screw Terminal Blocks for outputs
• External input voltage can be up to 30V at 500ma per channel
