SK Hynix H5TQ4G83AFR = 512M x 8 27 RMB that means EIGHTEEN dollars just in RAM ICs. that's if you can get hold of them.
RAM continues to be a problem to source.
I did tell / warn you.... :)
KiCAD version of R40 server board on a go slow pace at the moment - https://hellosemi.com/hypercube/pmwiki.php?n=Main.KiCADServerBoard (Some errors have left the power lines crossed in multiple places.) Also can't seem to raise Allwinner (no replies). Probably manage without tech support for now.
Yehh thats not a surprise, are you placing an order for 100k units? Then they might reply
In the mean time, been doing other KiCAD boards. A blue pill (ST clone of Atmega Arduino) - https://hellosemi.com/hypercube/pmwiki.php?n=Main. HypercubeBluePillSTDuinoBoard
You seen the board i did , right? Stl470? Akso can fund st cimmunity link for you they should be a long way along by now. Small form factor v cgallengung to get cost down.
2 layer st arduino clones are really tough to do
There is some infographic here about how to make intelligent Lithium battery packs for autonomous systems - https://hellosemi.com/hypercube/pmwiki.php?n=Main. HypercubeLithiumPrototypingBoard
And some info here about R40 boards for modularized AI + vision recognition and getting it to do some work with Arduino to do basic IoT work with it - https://hellosemi.com/hypercube/pmwiki.php?n=Main.AIBoards
All the other open source boards (or soon to be) https://hellosemi.com/hypercube/pmwiki.php?n=Main.OpenSourceBoards
