| 1 The board project contained in this directory was built in 2020-04 under highly | |
| 2 adverse political conditions. It is an LCD carrier board originally built to be | |
| 3 connected to the expansion interface on the historical iWOW DSK v4.0 Calypso | |
| 4 motherboard, also compatible with our FC Caramel2 MB built in the later part of | |
| 5 2020. The actual LCD module in this design is HaoRan HT020K1QC36S: out of the | |
| 6 two candidate LCD modules we had evaluated in the FT2232D MCU host bus emulation | |
| 7 setup back in 2018, this one was a little easier to use mechanically in a quick | |
| 8 low-effort development board like the one we needed to build in 2020-04. | |
| 9 | |
| 10 These HaoRan LCD modules appear to be no longer available (in our 2020 work we | |
| 11 used the last remaining sample pieces from the batch we got in 2018), but the | |
| 12 new LCD subsystem board being designed in the lunalcd2 directory (using a | |
| 13 different LCD module from a new vendor with whom we are engaging in 2021) is | |
| 14 hoped to be a satisfactory replacement. |
