AS5045 Demoboard
The AS5045 Demoboard is a complete rotary encoder system with built-in microcontroller, USB interface, 4-digit
7-segment display, a LED displaying the PWM output and two magnet status LEDs.
It also supports external AS5045 applications, such as the AS5045 adapter PCB or in-system AS5045 customer
applications that can be connected to the demoboard and displayed, modified and permanently programmed
using the AS5045 Demoboard Software.
The AS5045 demoboard can be used in several ways:
8.1.1
as standalone unit supplied by a 9V-battery
Connect a 7,5V..12V supply to pins "GND" and "+9V" at the right side of the board. No other connections are
required
8.1.2
as standalone unit supplied by an USB port
Connect the demoboard to a PC using a USB cable (included in demoboard shipment). The board is supplied by
the 5V supply of the USB port. No other connections are required
8.1.3
as input device for the AS5045 demoboard software
This configuration uses the same hardware connection as 8.1.2, but additionally the AS5045 demoboard software
is running. All indicators on the demoboard will be displayed on the PC screen as well.
