(I'm not sure whether 3.3V or 5V is correct for your stepper driver in the current configuration.. but you should be). Just keep breaking down the problem until you find the cause. | |

| Dec 7, 2022 at 15:24 | comment | added | Yumo | Hi, I just had a test with the points you mentioned, the coil pairs gave the same resistance as stated in the datasheet (3.6Ω for each coil pair, and around 3.9Ω~4.4Ω at the screw). The STEP signal works fairly as expected, the only concern is that its voltage level is 3.3V instead of 5V, I guess that's becase the click board has soldered the VCC SEL to 3.3V and I can't really physically change that. Right now I'm consider to use a DRV8825 so I can change those setting freely. | |
