BIGTREETECH EBB42 CAN v1.2 is an expansion board for 3D printers that allows easy and efficient control of the extruder. The board is designed for 42 mm extruders and is equipped with a number of functions that simplify and improve its control.
Key Features:
Easy Firmware Updates: With BOOT and RESET buttons right at your fingertips, you can swiftly upgrade the firmware via USB in DFU mode, making the process more user-friendly and enhancing the overall performance of your device.
Advanced Protection Circuitry: A built-in protective circuit on the thermistor acts as a guardian, shielding the main control chip from any damage that might be caused by leakage current from the heating rod, thus ensuring both durability and dependability.
Customizable Thermistor Resistance: Enjoy the freedom to adjust the thermistor's pull-up resistor values using a simple jumper wire. This feature supports PT1000 (2.2K pull-up resistors), allowing for a wide range of DIY projects.
USB Power Isolation: Power up your device via USB with a jumper cap, cleverly isolating the main control board's DC-DC converter from USB 5V. This smart move keeps electrical interference at bay.
I2C Interface for Smarter Detection: The dedicated I2C interface not only helps in detecting filament breakage and clogs but also supports a variety of DIY enhancements, broadening your creative possibilities.
Enhanced Voltage Protection: Anti-flyback diodes are strategically placed at the heating rod and fan ports to protect the MOS tube from reverse voltage damage, maintaining steady operation.
Secure Power Interface: An anti-reverse connection feature on the power interface acts as a safeguard, preventing any harm to the motherboard due to accidentally reversed DIY power connections.
Versatile Communication Options: Offering support for communication via both CAN and USB, you can select the terminal resistor 120R of CAN with a jumper cap. Plus, it provides CAN expansion interfaces for wider connection possibilities.
USB Port ESD Protection: An ESD protection chip on the USB port is your first line of defense against any static electricity damage, ensuring the long-term integrity of the main control board.
