Another good one!

Gus, I'm planning to come up and pay another visit in January. We should do an episode together? I'm currently building an IoT catapult. Maybe we could NETMF-ify or Octavo-ify it in some way?

@Gus - Thanks for doing these Gus. You have taught me some pretty exciting stuff so far. The variety is good. Please keep them coming.

Always have a chuckle when American's say the word soldering or solder, as the L becomes silent. In the UK we pronounce it "sowldering" and the W is to indicate that it sounds more like sow than saw. Smiley

Another way to solder them that is much faster is to do as Gus does with the 2 corners and then I apply tacky flux to the pins and then use a large tip with a ideally a concave face but a flat face one will do the job too. You then just flood solder along the edges on one continuous run. The flux helps to make sure the solder flows into the castellated pins. A quick spray with flux cleaner and you have a perfect soldered SOM. I used to do as Gus did but when hand soldering 10 boards it takes too long. Smiley

PS.. Have to add what cyberh0me said that focusing could be better Smiley

I remember when Gus made a soldering video centered around replacing the chip on the Fez Domi. This brings back memories.

Since the castelated pins are actually half holes, then would it be possible to use some sort of standard pin headers (either through hole or SMD) such that the module is removable?
