you do understand that 'better supported' in the case of the raspberrypi means that you are running a 32bit os? that's all they officially support - and have no plans to change

do you really think something or better and cheaper is impossible? the rpi is _the most overpriced sbc on the market_ particularly if you're not using it for raspbian (32bit only) and the module ecosystem

nanopi neo2 and rock64 are better and cheaper alternatives
