1.4 Application examples
UIO8AD board can be used to drive different elements if they don’t exceed 500 mA.
The following list shows the most common examples but is not exhaustive and specific applications can also be adapted.
Please refer to the datasheet of the element before using it.
1.4.1 DC motors
Board can b e used to drive DC motors up to 55 V and 500 mA, there is two ways to drive a DC motor (speed can be
modulated using PWM) :
• If one-way operation is used a single output can be used in open drain mode
• If both directions is used 2 outputs need to be used
Mode Motor UIO
One way + Vin
- Output 1
Two ways + Output 1
- Output 2

1.4.2 RGB LED
Board can be used to drive RGB LEDs, each color needs to be linked to an output so 3 outputs are used to drive a
single RGB LED (brightness can be modulated using PWM).

1.4.3 Relay
Board can be used to drive an external relay coils up to 55 V and 500 mA. Relay coil needs to be connected between an
output and a power supply.
