Indeed! And, as far as Marlin is concerned the TMC2225 and TMC2208 are the same, so it's *hopefully* a matter of 2208/25 vs 2209. Unless Creality did something completely off the wall...

# How to tell if I have TMC2208 or A4988 Drivers on Creality Silent V4.2.3 Board?

(Asked by: username_0 on 2021-12-15)

I have a new Creality Ender 2 Pro with a Creality 4.2.3 mainboard. I'm attempting to compile Marlin to fix a bug. How can I tell what driver chips I have on this board?

I've narrowed it down to likely `A4988` or `TMC2208_STANDALONE` or possibly the `TMC2225`. Strangely Creality only has documentation for the 4.2.2 and the 4.2.7 boards (not 4.2.3)

4.2.2 => TMC2208  
4.2.3 => ?  
4.2.7 => TMC2225

Some say you can tell the driver just by listening to the noise it makes. [Here is a video of the printer running](https://youtu.be/4hL-r02w6rM). The motors are nearly silent to my ear.

According to 'The-EG' comment in this GitHub issue, Add Creality Ender 2 Pro config #633, you can often determine the stepper drivers by one of a few ways:

Listen to the sound. The 'TMC22**' will sound much quieter

Look for a marking in Sharpie on the SD Card reader
C = HR4998
E = A4988
A = TMC2208
B = TMC2209
H = TMC2225


Remove the heat sync

After removing the heat sync, it appears that the Chip is actually a MS35775

MS35775 appears to be TMC208 compatible. You can find the data sheet on relmon.com here is the overview:

* 2-Phase stepping motor peak current of 2A
* Step / dir interface 2, 4, 8, 16, or 32 microstep
* Internal 256 micro steps
* Quiet mode
* Fast mode
* HS Rdson 0.29 Ω ,LS Rdson 0.28 Ω
* Voltage range 4.75 ~ 36V
* When the motor is still, it will enter into the power saving mode automatically
* Internal resistor mode is optional (no need for external sense resistor)
* Single wire UART bus and OTP control
* QFN28 package
