1 System Description

This design implements a digital back end for sensors and actuators. For communication to upper layers, the design makes use of 10BASE-T1L SPE allowing up to 1 km of cable length with 10Mbps data throughput.

Two options are available to power the design, either (1) acting as a PoDL PD being powered from the Ethernet lines, (2) or operating in stand-alone mode by attaching a 24-V power supply.

The Sitara AM2434 processor on the board allows implementation of powerful sensors or actuators with the possibility to perform processing of data, like fast Fourier transform (FFT) calculations directly on the edge.

The interface option of having a PHI and BoosterPack connector, allows the design to connect to the TIDA-010249 reference design which implements a four-channel integrated electronics piezoelectric (IEPE) vibration sensor front end. In the example shown in this design guide, the vibration sensor can be used for not only capturing vibration data of four analog channels, but also processing the data, like calculating an FFT and make decisions based on the results.
