TMC2209 has all the functions of TMC2208 and can completely replace TMC2208. At the same time, tmc2209 has better heat dissipation, supports larger current, and supports sensorless homing function.Continuing the characteristics of the TMC series driver, the mute effect is good, the chip has 16 segments, and the maximum segment: 256 segments.Larger driving current, the maximum current can reach 2.5A, and the stable printing current can reach 1.8A.Compared with other brands of TMC series drives, our drives have better heat dissipation.Support UART mode You can use UART mode in compatible with MKS SGEN L V1.0 / MKS GEN L V2.0 / MKS Robin E3D, SKR 1.3 / 1.4 by setting the jumper cap. No jumpers, no welding driver, more convenient to use, this function does not support MKS GEN L V1.0notes:1. Be sure to disconnect the power supply becompatible withe installing the drive to prevent the drive from burning.2. Be sure to confirm the direction of the driver becompatible withe installing the driver to prevent the driver from being damaged by reverse connection.3. Do not plug or unplug the drive module with power on to avoid damage.4. When installing the heat sink, pay attention to the contact between the heat sink and the pin header. Stop driving short circuit.5. The product is sensitive to static electricity, please handle it with care when using it, and it is best to move it again when using it6. Please also connect the power supply when measuring the voltage, dont just connect the USB power supplycolour: black + blueMaterial: metal + plasticPackage Contents:6 x TMC2209 stepper driver6 x heat sink (random color, dont accept the specified color)Note: due to different production batches, there may be some differences in products, which does not affect functional useOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
