I have bought a BTS7960 IBT_2 to control a motor (12v Linear actuator). But I have problems with the KC868-A6, not booting up correctly (Does not enable wifi, does not get online on HomeESP in Home Assistant) if I have added the BTS7960 IBT_2 from VCC to 3.3V port. I believe it might be because the BTS7960 IBT_2 need 5V and this puts to much load on the KC868-A6 to boot up correctly? Do you know if this issue, and do you know if my suspicion is correct. (If I connect the VCC to 3.3V after it has booted up and is active on wifi, it works fine with the motor)
From what I understand about the BTS7960 IBT_2, is that it should also with with 3.3V
To clearfy I am using KC868-A6-V1.4SP
Thanks!
Hej Schmidt,
- Does the board boots without BTS7960 IBT_2 connected to the board ?
- Are you using the firmware or your own code?
Hello Zali, I am using my own YAML code. Yes, the board boots normally, without the H-Bridge connected to the board.
But after changing power to 5V it works fine.
