Someone brick his switch while installing the SX CORE. Watch the video and avoid the same mistake
This guy lacks common sense. Why would you pretin those solder pads like that. Especially the anchor points make no sense. He could have just tinned them after he positioned the module.
Also lack of flux. None of the solder points he made actually looked like an acceptable connection.
I'm sure most people can solder this thing with just a little bit of practice. It is not too difficult if you have the correct tools.
