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.
