The EVAL-CN0554-RPIZ is a flexible, general-purpose multichannel mixed-signal analog input/output (I/O) module. The 16 single-ended analog outputs are software configurable, with ranges of 0 V to 5 V, ±5 V, 0 V to 10 V, and ±15 V. Eight channels of fully differential analog input are provided with hardware selectable input ranges of ±2.5 V and ±25 V. The circuit is designed to mount directly on top of a Raspberry Pi, providing this popular single board computer an analog input/output interface. Software control is accessible through the Linux industrial input/output (IIO) framework.
