4PCS MOSFET-Low calorific value, the maximum current can reach 20A.(because the module is limited by area, the current cannot exceed 5A) Upgraded version of TMC5160 V1.2, the heatsink can completely cover 4pcs MOSFET. The TMC5160 V1.2 uses a 6-layer board, which is more complete than the TMC5160 V1.1 signal, and the work is more stable and the heat dissipation is better. Ultra-quiet, avoid losing steps and jittering. Can drive 57 stepper motor. Only Support SPI working mode, currently only firmware for Marlin 2.0 and above supports the TMC5160 SPI mode.
