Mounting and deploying a Mini Pearl Logger
 |
| A completed Mini Pearl Pro Logger |
A Mini Pearl Logger is built by combining several off-the-shelf electronic components. Assembling a Mini Pearl Snap Logger Kit involves sliding DuPont wires onto header pins and takes about 15 minutes. Assembling a Mini Pearl or Mini Pearl Pro Logger Kit requires soldering wires between the components. In either case, the result can be sprawling and floppy.

All of the electronic modules in a Mini Pearl Logger have exposed pins and solder points, so to avoid shorts, the modules must be protected from one another. Stabilizing the assembled logger is also useful because it prevents motion at the wire connections which could break solder joints or loosen DuPont connectors. To address these issues, I designed a mounting plate for this logger.

| Figure 2. The Mini Pearl Mounting Plate makes it easy to stabilize a Mini Pearl, Mini Pearl Pro, or Mini Pearl Snap Logger. The components are attached with twist wires through the holes. Only the round holes are needed for the Mini Pearl Snap Logger, and the square holes are also used for the soldered versions. Triangular holes are for mounting the plate to something or for wire passthrough. |
 |
| Figure 3. Wires can be twisted under the mounting plate to hold the components securely. The yellow elastic cord will hold the battery case against the plate. |

All Mini Pearl Loggers ship with a 3D printed mounting plate.
