Overcoming the Limitations of Raspberry Pi with Support for Analog Inputs and Outputs
As the world becomes increasingly digital, the importance of analog functionality in industrial, instrumentation, and automation applications remains critical. Many applications require the ability to measure and interact with real-world devices, which are inherently analog. To operate at the boundary of digital and analog domains, processors must include mixed-signal inputs/outputs and accommodate more software programmable ranges to be considered for these applications.
One solution to this problem is a flexible, multichannel mixed-signal analog input/output (I/O) module that provides 16 single-ended analog outputs that are software configurable with ranges of 0 V to 5 V, ±5 V, 0 V to 10 V, and ±15 V. It also offers eight channels of fully differential analog input with hardware selectable input ranges of 0 V to 2.5 V, ±13.75 V, and 0 V to 27.5 V.
This module is designed to mount directly on top of a Raspberry Pi, providing this popular single-board computer with an analog I/O interface. The software control is accessible through the Linux industrial input/output (IIO) framework, providing a host of debug and development utilities, cross-platform application programming interface (API) with language bindings for C, C#, MATLAB, Python, and more.
The module’s software can run either locally on the Raspberry Pi or can be controlled remotely via a wired or wireless network connection. Additionally, the 5 V power for the module is supplied via the Raspberry Pi interface connector, eliminating the need for an additional power source.
This solution provides a low-power, precision analog I/O interface suitable for local and remote industrial applications. With its mixed-signal inputs/outputs, the module allows engineers to operate at the boundary of digital and analog domains, ensuring accurate and reliable measurements and outputs.
The ±10 V Analog Input and ±15 V Analog Output Expansion Board for Raspberry Pi platforms is an essential tool for engineers working in industrial, instrumentation, and automation applications. While the world continues to become more digital, the need for analog functionality in these applications remains critical. This module’s mixed-signal inputs/outputs and software programmable ranges allow engineers to operate at the boundary of digital and analog domains, providing accurate and reliable measurements and outputs that are essential for these applications.
