BTT EBB SB2240 CAN V1.0
Couldn't load pickup availability
BIGTREETECH EBB SB2240 CAN V1.0 is a Klipper toolhead board for Voron StealthBurner builds. It puts the extruder driver, hotend outputs, fans, probe/sensor wiring, ADXL345 accelerometer, and USB/CAN communication on the toolhead to cut the moving harness down to a cleaner CAN or USB setup.
Why use this board
- StealthBurner-specific layout: the EBB SB2240/2209 CAN V1.0 family is documented by BIGTREETECH for Voron StealthBurner toolhead use.
- TMC2240 version: onboard TMC2240 stepper driver in SPI mode for the extruder motor.
- Cleaner toolhead wiring: supports CAN bus or USB communication instead of running every hotend, fan, probe, and extruder lead back through the cable chain.
- Built-in input-shaper hardware: onboard ADXL345 accelerometer for resonance measurement in Klipper.
Specifications

Pairs well with
- U2C CAN Interface Board when your controller setup needs a USB-to-CAN bridge.
- BTT 3m CAN Bus Cable for a ready CAN harness run.
- Voron Stealthburner Fastener and LED Kit if you are refreshing the StealthBurner assembly around the electronics.
Gotchas
- This is the SB2240 / TMC2240 version, not the SB2209 / TMC2209 version.
- Use the VUSB jumper only when powering the board over USB for flashing or setup; follow BIGTREETECH wiring docs before applying printer power.
- CAN setup still requires correct firmware, termination, and host configuration. If you want simpler commissioning, check whether USB mode fits your build.
“Perfect, follow directions flashes as intended.”

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
