 1. This is a 3.3V logic device do NOT connect the I/O logic lines to 5V logic device.
 2. SW SPI pick any GPIO you like , HW SPI SCLK and SDA will be tied to MCU SPI interface.
 3. Backlight on/off control is left to user.
+4. NOTE: Connect LED backlight pin 1 thru a resistor to VCC.
 
 ## Tested
 
 Tested with both software and hardware SPI on:
 
 - **ESP32**
 - **Arduino UNO R4 Minima**  
-  *Frame buffer example is not supported on this board.*
-
+ 
 Compiled only (not fully hardware-tested) on:
 
 - **Arduino UNO**
 - **ESP8266**
 - **STM32 “Blue Pill”**
 
 > Some examples on low-RAM MCUs will fail( insufficient memory ), numerous fonts and bitmap data are included.  
-> Frame buffer mode requires sufficient dynamic memory for the buffer — see the README in display16_LTSM for details.
