Operation Manual
1 General Description
The reference design allows an easy and fast evaluation of the AS5600 rotary magnetic position
sensor in the lab. Additionally it is possible to replace an existing potentiometer with the AS5600SO_RD_ST. The module is fully assembled with and pcb including the AS5600 position sensor and
its necessary external components. All relevant signals are available on a 7-way connector
Connector and can be easily wired to an existing application. Additionally there are tree-pin header
to replace existing potentiometers.
The AS5600 is a programmable Hall-based rotary magnetic position sensor with a high-resolution
12-bit analog or PWM output for contactless potentiometers. Based on planar Hall technology, this
device measures the orthogonal component of the flux density (Bz) from an external magnet while
rejecting stray magnetic fields.
The default range of the output is 0 to 360 degrees, but the full resolution of the device can be
applied to smaller range by programming a zero angle (start position) and maximum angle (stop
position).
The I²C interface is used for configuration and user programming of non-volatile parameters in the
AS5600 without requiring a dedicated programmer.

2 Getting Started
The AS5600 reference design is a contactless potentiometer. It can be programmed in 3-Wire Mode
or over I2C.
2.1 Adapter Board Pin-Out
The pin-out of the adapter board is shown in Table 2. For additional information on the AS5600 pins
refer to the product datasheet.
