## Description

desertcart.com: BIGTREETECH EBB36 CAN Bus Adapter Board with MAX31865 Hot End PCB Board Filament Break Blockage Detection for 36 Stepper Motor Extruder Nozzle Head Tool for Blv Ender 3 : Industrial & Scientific

Review: Good sensor - This was quite easy to use after following a YouTube video. It performed its function as stated and I found it to be quite a good value for its price point.
Review: World flawlessly! - Wish it came with some documentation to explain the pin-out for people not using this on printers. Luckily Santiago posted the correct pin-out so I didn't have to go searching or wasting time with a multimeter trying to figure out which pin went where 😆! I'm also using this for a miniature wafer handling robot I'm building and I'm very impressed with the functionality for the price so far. The motor is extremely silent even at high speeds and has zero error, can't ask for more.

## Features

- Smart Upgrade: Onboard MAX31865, support 2-wire/4-wire PT100/PT1000 selection, support CAN or USB communication, among which CAN terminal resistance 120R can be selected by jumper cap, and reserved CAN expansion interface, reserved RGB interface , to meet the lighting needs
- Easy to Use: It is a 36-step (42-step) motor extruder nozzle adapter board, which can communicate through USB or CAN, which greatly simplifies wiring. BOOT and RESET buttons are reserved on the motherboard, users can enter DFU mode through USB to update the firmware
- Superior Security: The EBB series has been optimized in multiple dimensions in terms of security. USB power-on is selected by jumper cap, which effectively isolates the DC-DC and USB 5V of the main board, and increases the protection circuit of the thermistor part to avoid the burning of the main control chip due to the leakage of the heating rod. The USB port adds an ESD protection chip to prevent the main control from being damaged. Electrostatic breakdown of the USB port
- Rich Expansion Functions: I2C interface is reserved. This port can also be used for material breakage, material blocking detection, or DIY operations for other functions. The factory is equipped with terminals, female reeds, double-way studs and screws for Meet the DIY needs of customers
- About Product: Q: When updating firmware, it may be a risk that the heater sticks keep heating up A: please pay attention to disconnect the main power VIN of the hotend when using the DFU of Type-C port to update the firmware, or ensure that the firmware update is completed soon and goto the normal working mode. Never keep MCU in DFU mode for a long time when the main power supply and hotend are connected

### ⭐⭐⭐⭐⭐ Awesome and compact.
*by F***A on June 14, 2025*

Great little board. Used on a Sovol sv08 to convert to Can communication. Connectors used on this board are 2.5 pitch which makes a whole lot of difference with ease when comparing to the 1.5 pitch on the Sovol stock board. Easier to crimp in case you pull out a wire when disconnecting a connector and way easier to crimp. Simple installation when following the manual on the btt GitHub page. Though, having some experience connecting to your printer host via ssh and using the Linux command line helps. The heater terminals are also larger than the ebb36 board which also makes it easier to install the heater wires and using ferrule connectors. Using the board to connect an eddy dual, x endstop, filament sensor, extruder fan, two part cooling fans spit into one connection, neopixel leds, heater, and thermistor. Still have a few pins to use if something comes to mind. Good buy.
