GateKeeper is an open-source precision data-acquisition platform for 2D materials and quantum-device experiments, built around low-noise gate control and synchronized input capture.

The system combines eight true 20-bit analog outputs over a ±10 V range with eight 24-bit analog inputs. Output ramps and input acquisition can be buffered and synchronized by the Arduino Giga control architecture for long, repeatable measurement runs.

This page shows the lid-off hardware model. Drag the chassis to inspect the assembly, and use the numbered markers for a quick overview of the major internal boards.
