  • SD card & USB upload support

  • A 4.7kOhm 0.1% temperature sensor pull up resistor is used, PT1000 can be connected directly. For PT100, an amplifier board must be used.


In order to be compatible with some motherboards, such as RAMPS1.4, mini12864 is equipped with RST (R3) and KILL (R4) optional resistors. At present, some motherboards (S6/Spider) change the KILL to 5V. At this time, please make sure that R4 is not on the mini12864 (please remove it if it is on the board), otherwise pressing the button on the screen will cause a short circuit between 5V and GND, and long-term operation will cause the motherboard to be damaged.
