Problems getting the A6 to work. I'm using Elecrow shield on a Uno.
Before destroying something are the following points correct:
1. With the Uno, SoftwareSerial is required at 11500 baud.
2. power_key must be connected to +5V for a couple of seconds. The Elecrow board as a push button to do this. It is also tied to D7 which does nothing. Am I correct that the full 5V are needed so an Arduino output is not adequate. Is it also OK to permanently hardwire this connection so there is no need to press a button?
3. The Uno has an insufficient power supply for the A6. A separate 2A source is needed.
Thanks
