Re: Plastic boxes for Prototype board and the CubSat sized prototype

I just realized I put the support for the USB connector on the wrong end so I have changed it in this version. A new file may also solve your issue.

Chris, Here are STL files. The 64kb file is the box for the prototype board you have. Let me know if you see any changes that need to be made.

Update on PCB prototype
by Bob Stricklin 26 Oct '23

26 Oct '23

All, Regarding the prototype PCB that is being built, the assembly house did a 1X check on the parts vs the layout and came back with the attached list of issues. I have addressed these issues as stated under comments. The PCB was released to be manufactured. The lead-time is stated to be about 2 weeks. I also pushed a complete set of the design files to GitHub PacSat-Dev_Docs. All the parts needed are either in hand at the assembly house or they are on order (5 parts) with no issues on delivery known at this time. Jumper coax lines are also on order. I would expect it to take at least 2 weeks for the assembly folks to setup and assemble the PCBs once they are received. So we should see prototypes around the end of November or first part of December. Also attaching an assembly drawing I made with some details. The assemble house wanted a detailed assembly drawing so I made 3D cad views of several parts that were not already in KiCAD so they would show up in the 3D rendering of the PCB from and back. These are placed on the GitHub as STEP files. There is also an assembly drawing output from Kicad showing placement of the parts on the PCB to aid in assembly. I am documenting this so everyone knows what is going on and to maintain a full open source position. Bob
