Are you planning to buy one of these motor drivers? We have a full guide for you.
We are going to discuss key differences between them.
Overview of TMC2208
The TMC2208 is a silent, high-efficiency stepper motor driver designed for use in 3D printers. It is a direct replacement for the popular TMC2100, and it offers improved performance and quieter operation.
This driver offers a wide range of features, including stall detection, adjustable current, and sensorless homing. It also supports industry-standard step and direction inputs, as well as SPI and UART control.
The TMC2208 is capable of delivering up to 2.8A of motor current, allowing for high-performance and silent operation.
This makes it an ideal choice for those looking to upgrade their 3D printers. Also, it has the ability to detect and avoid motor stalls, which helps to reduce the risk of damage to the motor and the printer.
Furthermore, the TMC2208 is compatible with many popular 3D printer controllers, such as Marlin and Repetier.
Overview of TMC2209: What is it and how it works?
The TMC2209 is a stepper motor driver designed for use in 3D printers, CNC machines, and other robotics applications. It features a high-performance, low-noise, and low-vibration design, as well as an integrated micro-step interpolation up to 256 micro-steps per step.
The TMC2209 uses a combination of digital and analog components to ensure smooth, quiet operation. It provides a wide range of adjustable parameters and settings, allowing users to tailor the motor driver to their specific needs.

TMC2208 vs TMC2209: What’s The Difference?
Now that you know the features of these two stepper motor drivers, let’s take a look at the key differences between them.
The TMC2209 is rated for up to 2.8A RMS current, while the TMC2208 is rated for up to 1.2A RMS current. This means that the TMC2209 can handle higher current loads than the TMC2208. Does this difference affect the performance? Yes, this difference in current rating affects the performance of the stepper motors as they will be able to handle higher loads with the TMC2209 than with the TMC2208. This makes the TMC2209 a better choice for applications requiring more power, such as 3D printing, CNC machines, and robotics.
The TMC2209 has a larger step interval range than the TMC2208, meaning that it can support a wider range of microstepping resolutions. This makes the TMC2209 more suitable for applications requiring precise control, such as 3D printers and laser cutters.
The TMC2209 is rated for up to 45V, while the TMC2208 is rated for up to 36V. This means that the TMC2209 can handle higher voltage loads than the TMC2208.
The TMC2209 is compatible with Trinamic’s StealthChop2™ motion control software, while the TMC2208 is not. This means that the TMC2209 can be used with Trinamic’s motion control software to achieve smoother motion and better control.
While both have a QNF package, there is a slight difference in the mode of packaging. The most notable difference is that the TMC2209 has large heat sunk while the TMC2208 features a wattable QNF package.
There is also a difference in the braking mechanisms deployed by the two. TMC2209 has a passive braking system whereby the current is reduced when the stepper motor is not in motion, while the TMC2208 has an active braking system which uses an external resistor to dissipate the energy stored in the motor when it is not in motion. The passive braking system used by the TMC2209 is more efficient than the active braking system used by the TMC2208.
Dimension is all about size and the TMC2209 is slightly bigger than the TMC2208. The TMC2208 measures at 9.7mm x 9.7mm while the TMC2209 comes in at 11.5mm x 11.5mm.
Does the dimension matter? Yes, the dimensions do matter as they affect the size of the board or the space in which the stepper motor drivers can be used.
The TMC2208 is more suitable for applications requiring a smaller form factor, while the TMC2209 is a better choice for applications that need a larger size.

Is TMC2208 compatible with A4988?
No, TMC2208 stepper motor drivers are not compatible with A4988 stepper motor drivers.
While both are stepper motor drivers, the TMC2208 uses a different protocol, and is not directly compatible with the A4988.
However, it is possible to use a TMC2208 in place of an A4988, but it requires additional hardware, such as an STM32F0 board, and a separate control board to translate the commands from the A4988 to the TMC2208.
How do I enable TMC2208?
To enable a TMC2208 stepper motor driver, you must first connect the driver to the appropriate power and motor connections.
You can then use a suitable tool to send the appropriate commands to the driver to enable it.
To do this, you will need to connect the driver to a microcontroller or other compatible device, such as an Arduino. Once connected, you can send the appropriate commands from the microcontroller to the driver to enable it.
For more detailed instructions on enabling a TMC2208 driver, please refer to the driver’s product manual.
TMC2208 vs TMC2209: Which one should I choose?
The TMC2208 and TMC2209 are both stepper motor drivers, and the primary difference between them is the type of current control they offer.
The TMC2208 offers spreadCycle current control, which provides a smoother and quieter operation, while the TMC2209 offers stealthChop current control, which provides higher torque and faster acceleration.
If you need a quieter operation, then the TMC2208 would be the best option, while if you need higher torque and faster acceleration, then the TMC2209 would be the better option.
You may also consider the price. The TMC2208 is generally more affordable than the TMC2209, and may be a better choice if you are on a budget.
I hope that at this point you know the difference between the TMC2208 and TMC2209. You can now make an informed decision when it comes to buying these stepper motor drivers. As a general rule of thumb, ensure that you purchase from reliable suppliers in China such as ICRFQ.
