Re: refurbished IPad older iOS?

I think you might be safe with IOS 10 or higher. It was released in 2013 when Apple ditched 32 bit apps. Amazon sells refurb Mini 4 for $199

Re: refurbished IPad older iOS?

A moderately useful article about buying iPads past and present.
Not written from our point of view.

The app does indeed state it requires iOS 10.0. But my version on my iPad says it is the current iNavx version 5.5.2

Believe it or not, we still have an original iPad 1 cellular model with internal gps purchased two months following the iPads original release, is still running INavx with all the European charts installed. Of course, no updates in years but still functional.

To the OP, I wouldn't go any older than an iPad Air 2, but what I usually do and might actually do again this year, is purchase a 1-2 year old model for a significant discount off eBay which still has the AppleCare warranty in effect, then expect to get 6-8 years of service out of the unit.

Re: refurbished IPad older iOS?

I use a iPad Air 2 with real VNC to share the screen of a raspberry pi running openplotter over WiFi. The pi doubles as a WiFi access point. The pi uses maybe 1/2 an amp. The iPad maybe half an amp. I have an ais transponder that is interphase with the pi to overlay traffic on the charts on opencpn in the pi. Total cost was $185 for the ipad, $35 for pi, $200 for ais, plus Misc. stuff. The iPad is just a wireless interphase for the opencpn charting on the pi. I can be on the head and more or less see what’s going on. Ultra low power.

VNC is virtual network connection. You can share and use the screen from one computer, tablet, phone to another over a network. The type of iPad becomes more or less irrelevant as long as it can run vpn software compatible with the real VNC software running on the raspberry pi running the navigation software. The tablet is only used as a wireless screen and input device.

Re: refurbished IPad older iOS?

Running with a VNC is fine, but you’re not adding redundancy with that option. Only adding convenience. I think op was talking about using an iPad to get another independent system.

Re: refurbished IPad older iOS?

Running the navigation system off a raspberry pi makes redundancy cheap and easy. The pi power supply and sd card is less than $50 and can be down in the boat in a controlled environment. The ipad can be less than a few hundred dollars. Redundancy on the viewing screen (ipad) can be anything that will run VNC. I've run it on my Iphone, Ipad, Android, tablet, Macbook, Windows laptop. You get my point. This setup opens up a lot of redundancy and flexibility. The Pi and Openplotter/Opencpn opens up a lot of expansion with the 40 GPIO pins, 4 usb ports, and wifi connectivity for sensors, AIS overlay, and NMEA bus. I tend to use my Ipad as a navigation remote screen and a Ereader at the same time. Sometimes use my Iphone for a nav screen and run a movie on the ipad or visa versa at night.
