There are four mounting holes on the Woodpecker and the Robin. Plese refer to the datasheet for the position. On the Module Woodpecker and Robin the holes are connected to GND.
On the baseboard the mounting holes can be handled in several ways. For comparison the advantages are listed.
The standoffs may help to dissipate some power from the module over the baseboard. But the standoffs have a very small influence on the heat dissipation.
