| Jul 31, 2023 at 20:17 | comment | added | KIIV | How much current the TB6600 needs on its inputs? Bidirectional level shifters can't provide much current on the high side as they are basically shorting LOW through the mosfets (HIGH is pulled up by few kiloohms resistors to HV) | |
| Jul 31, 2023 at 18:04 | comment | added | 6v6gt | The inputs ENA, DIR and PUL appear to be leds of optocouplers based on this: dfrobot.com/product-1547.html . I guess that you don't need that logic level shifter which is anyway intended only for very low currents. It is strange, however, that 5v is specified. The wiring in the link I have supplied implies that LOW is on and HIGH is off. Ensure that any example code you are using matches your wiring. | |
