4. Assembly and connections
This chapter provides important information regarding the use of the Yocto-GPS module in real-world
situations. Make sure to read it carefully before going too far into your project if you want to avoid
pitfalls.
4.1. Fixing
While developing your project, you can simply let the module hang at the end of its cable. Check only
that it does not come in contact with any conducting material (such as your tools). When your project
is almost at an end, you need to find a way for your modules to stop moving around.
Examples of assembly on supports
The Yocto-GPS module contains 2.5mm assembly holes. You can use these holes for screws. The
screw head diameter must not be larger than 4.5mm or they will damage the module circuits. Make
sure that the lower surface of the module is not in contact with the support. We recommend using
spacers, but other methods are possible. Nothing prevents you from fixing the module with a glue
gun; it will not be good-looking, but it will hold.
If your intend to screw your module directly against a conducting part, for example a metallic frame,
insert an isolating layer in between. Otherwise you are bound to induce a short circuit: there are
naked pads under your module. Simple packaging tape should be enough for electric insulation.
4.2. Antenna
The antenna is a key element of your system. Make sure that it is always set up in such a way as it
can "see" the largest part of the sky possible. Except in particular cases, you cannot receive good
quality GPS signals from inside. However, if you really want to try, set the antenna near a window.
