Today I can introduce you to the development of our AZ-Touch: the AZ touch MOD. This one will replace our product "AZ-Touch ESP" from now on.
Benefits of AZ touch MOD:
+ The board is pre-mounted. All components (except the socket bars) are already soldered.
+The board has a preparation for another display box bar suitable for a 2.8 inch TFT touch screen display.
+ The prototyping area has been expanded.
+The layout has been adapted - the jumper for programming the ESP32 is no longer necessary and is not necessary.
+ The interrupt pin T_IRQ for the touchscreen is now connected to Port 27.
- For space reasons, the slot for the Amica V2 module was removed.

AZ touch MOD: Soldering
Since the components are already mounted on the board, only the sockets need to be soldered. These are all plugged on the top of the board and soldered on the bottom:

AZ-Touch MOD: Necessary customization of the software
The code examples for the AZ touch also run all with the new AZ touch MOD when the 2.4 inch TFT touch display is used.
Only the ESP32 must be used for theInterrupt pin T_IRQ will be changed from 2 to 27.
#define TOUCH_IRQ 2
