+  * 3.5" TFT display module. Most likely((See the chitusystems webpage, [[https://chitusystems.com/product/tft-touch-screen/]] which shows a picture of the SSD1963 display controller)) it is the Solomon Systech SSD1963. A datasheet of the Solomon Systech SSD1963 can be found here: [[https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/Solomon-Systech-LCD-Controller-Data-Sheet.pdf|Solomon-Systech-LCD-Controller-Data-Sheet.pdf]]. Also, I ordered a 3.5" TFT display from Chitusystems and it is compatible to and works on the Chitu FX board.
