What is the difference between TMC2209 and TMC2208 ? TMC2209 detects the motion blockade (Stallguard) and dynamically regulates the current supplied to the stepper motor, saving up to 75% of electricity. Stepstick based on the Trinamic TMC2209 chip. Compatible with StepStick and Pololu A4988 Up to 256 microstepping interpolation Current up to 2.0A (RMS) peak 2.8A Configuration via CFG or UART interface Motor voltage: 5-28V Logic voltage: 3.3-5V RSense: 0.11 Ohm StealthChop2 - Quiet operation and smooth movement SpreadCycle - dynamic motor control CoolStep - electricity control and energy saving StallGuard4 - sensorless motor load detection The set includes a heat sink and a cable https://elecena.pl/product/22607823/tmc2209-v1-2-stepper-motor-driver-by-bigtreetech 2023-02-22 https://elecena.pl/product/22607823/tmc2209-v1-2-stepper-motor-driver-by-bigtreetech 2025-10-29
