Home Arduino Module Sensor Chips About Us Item Description Features: 1.Chip model: TMC2225 2.The product is made of high quality material, quality is guaranteed 3.TMC2225 is the next generation of TMC2208, the main difference between TMC2208 and TMC2208 is that the package adopts HTSSOP instead of QFN, and the functions are identical. 4. With heat sink, better heat dissipation performance, more cost-effective 5. Support UART mode, no jumper required 6. Large drive current, maximum peak current up to 2.0A Driving current adjustment. 1.Vref measure the voltage of Gnd and the middle of the potentiometer. 2.Do not connect the motor when measuring the voltage, otherwise the driver will be easily burned. 3.Measure the voltage should be connected to the power supply, do not just connect the USB power supply. Driver current algorithm: l=Vref Default I=1.25A Uart Mode. UART mode can be used on GEN_L(V2.X), SGEN_L, set by jumper cap Purchase Notes: Batches are different, row of pins color shipment random.
