updated names. The table below lists the pins that have a changed name along with their old and new

2.2 Minimal design
This is a minimal design for a NEO-8Q and NEO-M8 series GNSS receiver.
Figure 4: NEO-8Q / NEO-M8 passive antenna design
NEO-M8M can support passive antenna, but for optimal operation it requires an external SAW and
LNA, see Figure 7.
2.3 Layout: Footprint and paste mask
Figure 5 describes the footprint of the NEO-8Q and NEO-M8 series modules and provides
recommendations (not specifications) for the paste mask Note that the copper and solder masks
have the same size and position.
To improve the wetting of the half vias, reduce the amount of solder paste under the module and
increase the volume outside of the module by defining the dimensions of the paste mask to form a T-
shape (or equivalent) extending beyond the copper mask. For the stencil thickness, see section 4.2.
