Deepsleep with Lopy4 on expansionboard

[iber]

I can't remember what the exact problem with the deepsleep issue was.
Because of the issue Pycom provided deepsleep shields free of charge for each affected device.
But was the problem with the expansion board or the microcontrollers themselves?
If I put a new Lopy4 on an expansion board from back then, does it still require the extra shield for deep sleep?

ok, thanks @ssmith

@iber No, it was for the LoPy module only. There was an issue with the power supply on those modules. No need for the shield with the LoPy4.
