You could easily make a $100 streaming machine. Cheapest 1200p portable monitor is $74 on Amazon. The SOC could use quad core A53 found in $15 Raspi Zero 2. That SBC has half the RAM capacity and its slower than LPDDR4 too, but the whole thing is sold at a good profit margin for low volume buyers, so the prices would likely end up the same. So does the afromentioned monitor, sold at a margin And a pair of hall effect analog modules is about $10 at amazon, should be way less in high volume straight from the manufacturer. And wifi 6 is pretty old and really cheap at this point, wifi 6 dongles are $10 in the commercial market, the components are way cheaper.
