Features: Simple wiring: Use MCU RP2040 to ensure reliable performances of CAN bus signals, which can support longer distances and high data rates without errors. EBB SB2209 (RP2040) adopts a PH2.0 socket, making crimping terminals easier and meeting StealthBurner's main expansion needs. The interfaces layout is reasonable and easy to connect. Quiet driving chip: EBB SB2240 CAN onboards TMC2240. EBB SB2209, SB2209 (RP2040) CAN onboards TMC2209. TMC2240 has rich diagnostic and protections functions, such as short circuit/open circuit protections, thermal shutdown, and undervoltage locking. Due to internal optimization, it can drive more current at lower temperatures, making the extruder run longer. MAX31865 onboards use PT100 or PT1000 temperature probes for precise thermal printing, with built-in ADXL345 allowing you to use input shapings function for perfect printing Rich expansion interfaces: two fans (FAN0, FAN1), unidirectional four wire fan interfaces. Two wire fan voltage can be selected simultaneously. heating rod interfaces, 5569-2pins, supports up to 5A current, and buckle type wiring is more stable. Support the use of BLTouch, Voron Tap, and more.
