Warm Tips: If the SKR 3 motherboard used with EZ series driver, you need to match the EZDriver Connect
Features:
1) 32-bit 480MHzARM-class Cortex-M7 series main control chipSTM32H743VIT6, with betterperformance.
2) With power supply chip TPS5450-5A, DC12/24V power input, output current up to 5A/6A, perfect power supplyforRaspberry Pi
3) Works with all serial screen, SPI screen and LCD screenof BIGTREETECH.
4）To upgrade configuration firmware bySD card, easy and efficient operation.
5) On-board SPI working mode and UART working modedriven by TMC; on-board DIAG pins, which can be used by unplugging jumper caps.
6) With resume printing, filament breakdetection, autoshutdown, BLtouch, RGB light and other functions.
7) Adopting high-performance MOSFET tubes to reduce heat generation.
8) The fuse are easy to replace.
9) Adding protection circuit for the thermistor to avoid burning ofmain control caused by hot bed or heating cableleakage.
10) WIFI module (ESP12S, ESP-07, ESP32) common interface for customers to DIY and useRRF firmware.
11) On-board TF card slotwithout self-ejectingand SDIO working modeimprovethe transmission rate.
12) Reserved BOOT0 buttonforcustomers to use DFU mode, convenient for customers toburnfirmware through DFU mode.
13) On-board EEPROM, convenient for customers to adjust and save parameters.
14) As for CNC fan,there is24V, 12V, 5V voltage selectionof the external power supply module , easy to operation, avoiddamage to the motherboard.
15) Theresistance valueof thermistor can be selected through the jumper. Support PT1000, without external module.
16) Reserved two CAN interfaces, USB port and XH2.54 6Pin terminal interface
The Differences between SKR 3 Motherboard and SKR 3 EZ Motherboard
- Different product sizes. SKR 3's product size is 110*85mm, and its installation size is 102*76mm. And SKR 3 EZ's product size is 109.7*98mm, installation size is 102*76mm.
- Distinct High motor voltage. SKR 3 motor voltage is from DC 12V to 24V, while SKR 3 EZ motor voltage is from 12V to 48V. You could adjust it with a jumper cap. The high voltage can extremely improve your printing speed. What's more, SKR 3 owns 2 normal fans, and the EZ version owns 3 normal fans, which can ensure the smooth operation of your printer and advance your printing quality.
- Different means of connection. In the SKR 3 you can use the drive connector to use our newly designed EZ drive. However, the SKR 3 EZ can be plugged directly into the EZ drive without the need for a converter. the EZ drive is designed to provide excellent protection for your fingers from sharp pins. What's more, this wonderfully protective anti-plug design will help you protect your motherboard. Because of the feedback received, some customers have fried their drives and motherboards due to incorrect insertion and even caught fire in some serious cases. That's why BIGTRETECH has created this upgraded drive technology.
