BIGTREETECH DIRECT TMC2209 V1.2/V1.3 Stepper Motor Driver Silent UART Stepsticks VS TMC2100 TMC2130 for SKR 2/ SKR V1.4 Turbo Manta M4P Manta M5P/M8P 3D Printer Motherboard (Pack of 4pcs)

Ordered uart set but it wasnt soldered as such, as a few others have experienced

It’s probably not the drivers fault, but the BTT Octopus board wouldn’t acknowledge these steppers. I give up on BTT and Biqu. Returned everything and changing brands

These are so quiet compared to A4988 drivers that I didn’t realize the motor was moving. Good packaging and nice included heat sinks in pretty blue. Nice!

Worked perfectly for my Tenlog Printer. I had a fan fail and the heat smoked the 2209 chip for Extruder E1. Ordered the 4 pack and attached 2 of the packaged heatsinks for extra cooling and I was off to the races in under 20 minutes.

So I have to say right out of the gate that Biqu was great about replacing the motherboard on my printer when it failed. The failure also caused the print head/hotend to gum up real bad and it was pretty well ruined, and they replaced that as well. When swapping out the stepper motor drivers I likely ruined one unless it got damaged when the motherboard failed. Either way, I ordered these on my own to replace the ones that came with the original motherboard. THEY WORK GREAT! They literally are plug and play and my stepper motors are super silent. If you want to upgrade or just replace failed stepper motor drivers, these are an excellent choice.

Great steppers for drop-in replacement of Pololu boards. Very quiet and heat sinks are effective.

Hi Quality parts, definately worth the money... and the kids love the little rubber ducks.

I purchased these for a CNC build, but ended up using them on my FDM 3D printer. Performance is excellent & highly recommended.

Got these as spares for my btt skr 1.4 turbo boards.. have been running my printers pretty hard lately and like spares on hand, zero failures to date though so these will probably just sit on a shelf forever.

Silent, with sensorless homing. Easy to install, clear instructions
