Description: This project is adapted from the preliminary design for the “AEC 9005-110-X Low Volts Monitor Module” by Robert L. Nuckolls III. The board simply monitors the connected bus voltage and provides a 1Hz flashing output to drive a warning LED in the event the monitored bus goes below 13V.
This project is intended for use in Experimental category aircraft only. Do NOT install it in a CAR Part 3 or FAR Part 23 certificated aircraft without FAA Field Approval.
BOM: Cost is ~$8 for the components to populate this board. Click for a Digi-Key saved list with those parts.
