BTT BigTreeTech motherboard SKR 3 EZ v1.0
SKR 3 EZ V1.0 mainboard is 32bit 3D printer mainboard updated by Shenzhen Biqu Technology Co., Ltd. team for EZ series drivers based on SKR 3. It is compatible with both EZ series drivers and TMC series driver
It uses 32-bit ARM Cortex-M7 STM32H743VI series control chip with 480MHz main frequency.
The power chip adopts TPS5450-5A which supports DC12 / 24V power input. The output current of the chip is up to 5A and the peak value can reach 6A, which perfectly supports the Raspberry Pi power supply.
The numerically controlled fan carries out the selection of 24V, 12V, 5V through the external power supply module, eliminating the need for the customer's external transformer module, thus reducing the probability of damaging the motherboard.
The thermistor can select the value of the pull-up resistance with a jumper, and thus operate the PT1000 without the need for external modules, which is convenient for customers to do by themselves.
Supports features such as resuming printing, filament out detection, shutdown complete, BLTouch, RGB lighting, etc.
WIFI module (ESP-12S, ESP-07, ESP32) general interface.
Built-in EEPROM memory
Two types of CAN interfaces are reserved, the USB port and the XH2.54 6Pin terminal interface. USB port is for CAN and USB selection by two-pole bidirectional switch, which is convenient for customers to use other CAN interface accessories.
The motor power supply supports up to 48V, and for more voltage when using the TMC5160 and EZ5160, the isolation chip is used to protect the motherboard from burning IO.
