 **Note:** If using RGB LEDs, make sure they are the '​common anode' type. Then pin 37 or 38 (depending on LED voltage) can be used for anode and each RGB cathode is connected to individual LED pins (17-36). **Note:** If using RGB LEDs, make sure they are the '​common anode' type.

 +**Note:** If LEDs require voltage higher than 5V DC, an external power supply can be used up to 30V DC. Simply connect external power +ve to the Anode pins of the LEDs, and the external power supply -ve to pins 39 or 40 (ground) of SW16. Cathode of LEDs still connects to the appropriate LED pin on SW16 (pins 17 - 36).
