HI-8470 Evaluation Board.
The Holt HI-8470 Evaluation Board demonstrates features of the HI-8470 16 channel discrete-to-digital sensor with ARINC 429 transmitter. The board and the HI-8470 can be run from a single 3.3V +/-5% supply voltage. The device has preset internal sensor thresholds; external thresholds can also be set with board-mounted potentiometers. The HI-8470 and Evaluation Board require no software for control; all functions are set by hardware switches. DIP switches configure the device and data inputs.
