TMC2209 V2.0 Stepper Motor Driver Module with Heatsink

Key specs & features:

• Input motor-supply voltage: ~5.5 V to ~28 V (many modules list 5.5–28 V) 

• Logic (V_IO) supply: compatible with 3.3 V and 5 V logic.

• Drive current: typical RMS ~2 A, peak up to ~2.5–2.8 A (depending on cooling / module)

• Microstepping capability: up to 1/256 with interpolation (via the TMC2209 chip) 

• Features of the TMC2209 IC: “StealthChop2” for very quiet operation, SpreadCycle for dynamic load, sensor-less homing capability (StallGuard4), CoolStep for adaptive current.

• Comes with a heatsink (on the module version) which helps dissipation when using the higher currents.
