The P3 works a bit faster then the P2. Yesterday there was an update of the bootloader.
Result: faster screen
movement with OpenCPN on the P2 and the P3.
The P3 is running hotter then the P2. You can add a heatsink.
I'am using the beautifull alu case from Flirc, which has an alu pillar with a foam pad connected to the processor. The alu casing is working as an heat sink.
Not tried the wireless on the board inside the alu casing. I don't think this works.
The OpenPlotter has a lot of features and can run without a screen
as an NMEA/AIS server or with a remote
computer, tablet, Ipad
, as a wireless VNC client.
Here at home running AIS
via RTLSDR dongle. Also connected via an aktiv hub to the Raspi.
