The board project contained in this directory was built in 2020-04 under highly
adverse political conditions.  It is an LCD carrier board originally built to be
connected to the expansion interface on the historical iWOW DSK v4.0 Calypso
motherboard, also compatible with our FC Caramel2 MB built in the later part of
2020.  The actual LCD module in this design is HaoRan HT020K1QC36S: out of the
two candidate LCD modules we had evaluated in the FT2232D MCU host bus emulation
setup back in 2018, this one was a little easier to use mechanically in a quick
low-effort development board like the one we needed to build in 2020-04.

These HaoRan LCD modules appear to be no longer available (in our 2020 work we
used the last remaining sample pieces from the batch we got in 2018), but the
new LCD subsystem board being designed in the lunalcd2 directory (using a
different LCD module from a new vendor with whom we are engaging in 2021) is
hoped to be a satisfactory replacement.
