Product Information
Are you in Australia and seeking to purchase a BigTreeTech SKR 3 EZ 3D printer control board? The BIGTREETECH SKR 3 EZ V1.0 motherboard is a 32-bit marvel. Updated by Shenzhen Biqu Technology Co., Ltd.'s team for the EZ series drivers based on the SKR 3, it's compatible with both EZ and TMC series drivers. Key features include a 32-bit ARM Cortex - M7 series STM32H743VI main control chip running at 480MHz. The power chip, TPS5450 - 5A, supports DC12/24V input with an output current up to 5A and a peak of 6A, ideal for powering Raspberry Pi. The numerical control fan allows 24V, 12V, 5V voltage selection via an external power module, reducing the need for an external transformer and motherboard damage risk. You can select the pull - up resistance of the thermistor via a jumper and support PT1000 without external modules, great for DIY. It supports functions like resume printing, filament runout detection, completed shutdown, BLTouch, and RGB lights. There's a general interface for WIFI modules (ESP - 12S, ESP - 07, ESP32), onboard EEPROM, and two types of CAN interfaces (USB and XH2.54 6Pin terminal). The USB port uses a double - pole double - throw switch to choose between CAN and USB, convenient for using other CAN - interface accessories. The motor power supply can handle up to 48V, and with an isolation chip for TMC5160 and EZ5160, it protects the mainboard from IO burnout.
Using the BigTreeTech SKR 3 EZ 3D Printer Control Board is easy. First, connect the power supply. Make sure to choose the right voltage according to your needs - it supports DC12/24V. If you want to use a Raspberry Pi, the power chip can handle it. When it comes to the numerical control fan, just use the external power module to select the right voltage (24V, 12V, or 5V). For the thermistor, you can set the pull - up resistance value using the jumper. As for the WIFI module, you can use ESP - 12S, ESP - 07, or ESP32 and connect it to the general interface. When using the CAN interfaces, you can switch between CAN and USB on the USB port with the double - pole double - throw switch. For the motor power supply, be careful not to exceed 48V, especially when using TMC5160 and EZ5160. Maintenance is simple. Keep the board clean and free from dust. Check the connections regularly to make sure they are tight. If you notice any overheating or strange noises, turn off the power immediately and check for problems.
