My pin header made the soldering trickier than usual, maybe it soaked a lot of heat? Just remember the header needs to go on the ‘wrong’ side and take your time.

The Pi Zero upgrade is hardly used currently but the ZX Next team keep hinting at future utility, and at least one game is in development that uses it as a kind of math coprocessor.
