Product description

  • Main Control Chip The main control adopts the 32-bit ARM Cortex-M4 series STM32F429ZGT6 chip with a frequency of up to 168 MHz. The external crystal oscillator is 8MHz.
  • About Using Firmware Three types of firmware, Marlin2.0, killper, and RRF are supported. Please note STM32F429ZGT6 MCU flash memory space is 1MB, so all functions under the three firmwares are supported, including RRF firmware.
  • High Temperature Test The onboard MAX31865 can support 2 4-wire PT100 PT1000 temperature measurement without welding (the soldering resistance can also support 3-wire PT100 PT1000 temperature measurement)
  • Support Proximity Sensor Support proximity sensor, jumper optional pull-up resistor, support more models. This function can be sensed without touching the hot bed, while BLTouch needs touch sensing.
