TachoPin
TachoPin is a compact electronic interface designed to convert engine tachometer signals into standardized digital data for instrumentation, data logging, and control systems. It is used in automotive dashboards, industrial machines, and hobbyist projects to provide reliable RPM measurements and timing signals.
The device accepts common tachometer signal formats, including open-collector or push-pull square waves, as well as
Design variants include standalone modules and pin-compatible interfaces designed to plug into microcontroller projects. Calibration procedures
History and usage: The term TachoPin refers to a generic interface rather than a single manufactured product.
