NOTE: This readme will be extended soon.
This repository contains the KiCad files for an interface board between four piezo disk level sensors and an 3D printer. Its based on an ATMega328P that might either be powered from an existing 5V power rail or via the optional on board power regulator. It allows interfacing via I2C to perform settings and calibration as well as an traditional trigger output (for example to interface directly with an RAMPS board) and an trigger input for a classical inductive or capacitive leveling sensor.
More information can be found at my webpage.
Each piezo is biased independently.
