This adapter board shield (HCARDU0098) is intended to be used with our 3.2" TFT touch screen module (HCARDU0097) which is also available for purchase via our website. This shield allows the TFT screen to be easily interfaced with an Arduino Mega. It also includes level shifters to provide correct 3.3V voltage level interface to the screen. The shield also provides support for the screens resistive touch sensor and SD card interface and is compatible with our HCTFT TFT library when used with an Arduino Mega.

Can this adapter also be used with the 2.4" display HCARDU0083 - 01? The info provided on that page points to this adapter for the Mega but the info on the adapter page states that it is for the 3.5" display. Thank you.

Thanks for pointing that out. I't looks like a cut and paste error from the 3.2" screen page. It's now been corrected to point to the correct adapter shield.

To answer your question the adapter shield for the Mega is hardware compatible with the 2.4" screen but our HCTFT library doesn't support this combination. So for a Mega you would either have to use the 3.2" (HCARDU0097) screen with this adapter shield, or you would have to create or modify the HCTFT library to work with this combination.

There may of course be some existing software/library that may work with this combination but I'm not aware of anything.
