Sentry Controller (standalone) [Version 3]

Status: Discontinued
Reason: Outdated version

This version of the standalone controller was the first one to leave the prototyping stage and enter production.
Note that many of the components are PTH.
In addition, v3 required a small greenwire fix to enable the USB auto-reset function.
Surplus PCB's from this version are still available for purchase here.

  • Replaces the Arduino + Sentry Shield combination with one simple, all-in-one solution, for a lower price.
  • Plug-in connections for the three servo motors: trigger, pan, and tilt.
  • Three control switches: Aim, Safe, and Reload, with optional bypass solder points.
  • Supports an electric-type trigger, providing solder points for wires to the gun battery and the gun motor.
  • Standard 5.5mm power jack for servo power, with optional bypass solder points.
  • Provides solder points for wires to an optional 'disable plate' button.
