Product description

Product description
Specifications
Interface: Step/Dir
1. Configuration: CFG Pins or UART
2. Native Microsteps: up to 1/256
3. MicroPlyer Microsteps: 1/256
4. Logic Voltage (VIO): 3-5V
5. Motor Voltage (VM): 4.75-36V
6. Motor Phase Current max: 1.2A RMS, 2.0A Peak.
Therefore, the reference voltage of the driver module should not exceed 1V. At the same time, the driver module must be dissipated, otherwise it will affect the life of the driver module.
7. Internal V- Regulator: enabled
8. RDSon: 0.3 Ohm
9. StealthChop (quiet): yes
10. SpreadCycle: yes
11. MicroPlayer
12. CoolStep: no
13. StallGuard: no
14. DcStep: no

Motor Current Setting
The best way to set the motor current is by measuring the voltage on the Vref pin (0…2.5V) and adjusting the voltage with the potentiometer. The maximum settable motor current is 1.77A RMS (0.11Ohm sense resistors), but the SilentStepSticks can only be used up to 1.2A RMS. Irms = (Vref * 1.77A) / 2.5V = Vref * 0.71
Vref = (Irms * 2.5V) / 1.77A = Irms * 1.41 = Imax
Vref -gt; Voltage on Vref pin
Irms -gt; RMS (Root Mean Square) current per phase (Irms = Imax / 1.41)
Imax -gt; Maximum current per phase (Imax = Irms * 1.41)

Package Includes:
4 x TMC2208 Driver
4 x Heatsinks
4 x Screwdriver
