not at all: i've literally gone straight from learning of the
existence of the RK3288 to starting the PCB layout in under 24 hours.
i'm working on the assumption that a higher-end processor, larger
amount of RAM and larger amount of NAND (eMMC) will be desirable
regardless of cost. the required RAM ICs to reach 4 GB RAM are going
to be the $9 *PER RAM IC* variants. that's $36 just in RAM ICs - more
than the entire BOM for the EOMA68-A20. 32gb eMMC is also going to be
equally costly, and likewise the processor.
