Hi
I’m now working with a 3b+. On my 3b I had been using a cheap hub for a usb gps, and usb AIS and wireless mouse. I also fried my first 3b+ including IMU and micro SDcard, a few weeks ago, after it was splashed through an open port in the Thames Estuary. I’d been using it as a cable feed to test a homemade AIS aerial.
I’ve now stopped using the hub and am using the 3b+ USB ports including gps, sdr radio (AIS), a secondary wireless usb and Osenc charts and an IMU, without any indication YET of a current draw problem. I’ve not used the AIS at sea yet. I have however tried the Gqrx radio (the processor useage goes up close to 100%) without any indication of current draw issues so far. I’m also pleased with RealVNC which I use with my iPad Air.
I must stress that I’m still on a learning curve so my expertise is not very advanced.
