Hi,
I'm a student in melboune and would love to begin experimenting with TTN here. I've been hearing about lora/lorawan for a couple of years and would love to learn by experimenting. Looking at australian forum posts I'm struggling to find information on a budget gateway setup thats newer than 2019/2020. Could someone point me in the right direction please as I'm just barely starting to wrap my head it but am still a complete newbie?

As a first project I would like to add a GPS tracker to my mountain ebike using the device below:

I selected the device above as I can program the esp32 chip to derestrict the 25km/h speed limiter on the bike for offroad stints as per this link
https://github.com/NorthyIE/DasKit-C7BB-Tuning
along with hiding the setup inside the frame (curious to see if being inside the alum frame helps or hinders the antennas).

I would also like to add a gateway to the network. Initially I thought something like the Things Industries Indoor Gateway 915MHz TTIG-915-AU
https://au.rs-online.com/web/p/communication-wireless-development-tools/2018877/
would get me started, but is there a newer better budget option? Most of the time it would be plugged in upstairs near a window but I liked the idea of adding an antenna and powering it off usb-C for a mobile device.

I would love some advice on my choices above and any better budget options that I haven't come across.
Also, I'd really appreciate of someone could give me an in a nutshell insight to the items below
1/ v2 vs v3 stack, should I ensure whatever gateway I select is compatible?
2/ For the ESP32/LoRa device above, if I select the 915MHZ version, should this theoretically work on both US and AU networks or do I need an AU specific one?
3/ Single or multi channel gateway
