Great surprise at the current delivery of the OSPi: There is no longer a battery holder on the circuit board.
But still comes with a battery?
The solution is very simple: This is the new version die OSPI 1.44 and it no longer needs a battery.
The battery was for a component, the RTC (Real Time Clock), which was never used since the time always comes from the Raspberry Pi.
So this has now been removed.
“why is a battery in the package?” (why is there a battery in the pack), I asked the manufacturer, “Well forgot to take them out”
