Sentry Controller (standalone) [Version 3]


Status: Discontinued
Reason: Outdated version

Notes:
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.
