🐙【TMC2209 Driver Features】The TMC2209 stepper driver is not easy to lose steps and is in an ultra-quiet mode; the module has a large area of heat dissipation pad, which can reduce the temperature of the driver when it is working; the module supports three modes: STEP / DIR and UART.
🐙【TMC2209 Driver Mode】TMC Motor drivers can be used in SPI or UART mode by simply adjusting the onboard jumpers beneath each motor driver. Additionally, you can connect or disconnect the TMC DIAG pin using an onboard jumper allowing you to use hard end-stops or sensorless homing without the need to cut any pins.

GREAT FETURE BUT THE DOCS ARE BAD, clearly no documentation. but features. LEARN FROM FYSTEC PLEASE
BIGTREETECH Octopus V1.1 Control Board for Voron 2.4
The amount of features this board has is top notch. The versatility is hard to beat. Also, this company stands 100% behind its products. Highly recommend!!
These motherboards are probably the best, 32 bit, TMC 2209 or faster and wifi all on board. Matched with a touch screen and the raspberry pi 4 this finish the printer with the best solution
