Features: Brand new and high quality Using high-performance, 32-bit, 64 MHz MCUs STM32G0B1CBT6 from the industry leading ensures rock solid performances with CAN bus signaling that can support high-data rates over longer distances without errors. EBB SB2240 CAN onboards a TMC2240.The TMC2240 features abundant-diagnostic and protections features, such as short/open circuit protections, thermal shutdown, and under-voltage lockout. Due to internal optimizations, it can drive more current at lower temperatures, keeping your extruder running harder for longer. Drop-in Installation, Careful header spacing and location mean that wiring will be a breezed. No need to solder anything thanks to the onboards header-pins. SPI-Out interface is reserved, the installation position of the modules is flexible to meet more DIY usage scenarios. more bed leveling option, supports microprobe.
