With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.<br/>2. Added protection circuit on the thermistor avoids burning the main control chip caused by leakage current from the heating rod.<br/>3. Connect the USB witha jumper cap to get it power on, which effectively isolates the main control board DC-DC from USB 5V.<br/>4. Reserved I2C interface allows for filament broke and clogged detection, and supports other DIY functions.<br/>5. Added anti-flyback diodes on the heating rod and fans' ports effectively protect the MOS tube from being burned due to reverse voltage.<br/>6. Anti-reverse connection protection on the power interface prevents users from burning the motherboard when mistakenly connecting the reverse power line during DIY.<br/>External Dimensions: 40mmx 40mm<br/>Installation Dimensions:Hole spacing 31mmx 31mm, M3 screw holex 4<br/>Microprocessor: ARM Cortex-M0 STM32F072C8T6 48MHz<br/>Input Voltage: DC12V-DC24V 9A<br/>Logic Voltage: DC 3.3V<br/>Heating Interface: Heating Rod (E0), maximum output current: 5A<br/>Onboard Sensor: ADXL345<br/>Colour:As shown<br/>Material:PCB<br/>sytle:EBB42 / EBB36<br/>Due to different batches, there may be differences in product appearance and printed text, which will not affect use<br/><br/>Package Contents:<br/>1 * Extruder Breakout Board Kit<br /><br />Only the above package content, other products are not included.<br />Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
