This enclosure was designed to be an all-in-one solution for an Astroberry/Stellarmate powered OAT. It is future proofed as much as possible to allow extra motors/connections.
It has quite a large volume (~2200 cubic cm), has an internal removable/replaceable panel to allow customizing mount points for different boards.
¶ Features
- Arduino Mega
- LCD Shield w/ buttons
- RPi4 for Astroberry, Stellarmate, or whatever other control OS you use.
- Powered USB hub
- Isolated Power Section:
- Removable panel separating each section of the box to protect components that may have exposed higher voltages (the line side of the buck converters)
- Space for multiple buck converters for multiple voltages depending on what is needed
- Ventilation openings
- Note: a STEP file is provided so the removable panel can be customized to suit your buck converts/equipment.
- Two Decora sized openings to house keystone inserts (up to 6 keystone jacks each).
- Decora or "decorator style" inserts are very common in North America, but may be difficult to find elsewhere.
- This allows many different uses, e.g. USB ports to connect cameras to a RPi4, etc.
- Supported motors:
- RA, DEC
- AZ, ALT
- Space for whatever else you need to include:
- GPS module
- Battery storage
- Etc.
¶ 3D Printer Files
The STL and STEP files can be found here:
https://github.com/OpenAstroTech/OpenAstroTracker-Addons/tree/master/Enclosures/Astroberry All-in-One Box
The Arduino buttons file "buttons.stl" can be found from this design: https://www.thingiverse.com/thing:4253325
The box should be printed with supports for the Decora openings, but everywhere else will print fine without supports. If you set the support overhang angle to 85°, it should prevent supports from being generated anywhere except those openings (as the overhang is 90°).
