moitessier hat - AIS reception varies by power source

[Rooney]

... well nobody used the Pico .... but how about the StromPi3 ? - anyone used/tested the StromPi3 with the accu add-on on top of the Moitessier hat?

Hi,
I've not tested the StromPi3 yet, but according to the schematic of the StromPi this should work. However, the rechargeable battery must not be on top of the Moitessier HAT. This would dramatically reduce GPS performance. The HAT does not provide the 40-pin IO header on top anyway.
