3. Powering up the SF33

The SF33 gets power from either a regulated +5 V DC supply on the main connector or via the USB port when it is connected to a PC.
There are a number of digital and analog interfaces on the main connector and either one or a combination of interfaces may be
connected to a host controller. The built-in micro-B USB port can be used to input settings and to test the performance of the SF33.
Power supply option 1: USB
The SF33 can be powered directly from the USB port of a PC or laptop. This is particularly useful for testing the SF33 before it is
installed in your system and also for changing the settings in readiness for the final application.

Power supply option 2: Regulated +5 V DC
The second power supply option is to connect a regulated voltage of 5 ± 10% V DC to the main connector. If the power wires are more
than 30 cm long, we recommend using a decoupling capacitor, or other noise suppression components to reduce the chance
interference being picked up or transmitted by the wires.
