__TS_HEADLINE__
Mitgelieferte Antennen sind für viele Zwecke gerade ausreichend. Externe, bessere Antennen sind in diversen Fällen notwendig.
Ungeschickt:
- das PPS-Signal wird nicht an einen der GPIO-Pins weitergereicht.
- der HAT bietet keine Möglichkeit nicht genutzte GPIO-Pins anderweitig zu nutzen.
- alle Signale gehen über einen UART-Anschluss -- sortieren muss man selber -- das kann Schwierigkeiten bereiten, wenn GPS, GSM und Bluetooth parallel genutzt werden sollen. Hier wäre es sinnvoll gewesen entweder min. zwei UART zu nutzen oder diese über einen integrierten USB-UART-Baustein getrennt zur Verfügung zu stellen (also GPS über den eingebauten UART; GSM über einen via USB angebundenen UART-Baustein)

Hardwar OK, verlangt aber Bereitschaft Hand anzulegen.
