Ooops, sorry thought this was on the post I put on Can you delete all three?

OK. I now understand there is a capacitor on each type of l298n I have used. The one I have been using is 100 and the other with the heatsink has bigger capacitors.

I now wonder if this is why the motor can run fast for a bit, perhaps during that time the capacitor on the motor controller ...

Thanks for input. I am not getting the brownout message mine is TG1WDT_SYS_RESET

Here are the reset codes, mixed in with a few message of my own to try and see what is going on

Hi Becorey. I didn't understand.

My motor should go in both directions, do I put the capacitor on the input to the motor controller, or can I get a big enough one to go on the motor which does not have polarity? The diddy one across the motor terminals is to reduce noise, I'm not expecting it to ...

Just to clarify the motor is a 0 - 6v "high torque" motor. It is in a garden railway loco and the standard set up for the kit would just be an on/off switch giving 3v. So it is not a big motor.

Another thought. Could it be the mini motor controller is not as well behaved as a bigger one? I have a ...

I did expect to see the brownout message, but it is not there. So I am not really sure why it resets. I think it reboots twice, and then works. I am very new to this. I've broken a couple by forgetting to disconnect the usb when I put a 9v battery on v5.0 (hopefully I am getting wiser :) ).

I am ...

I have what I think is the minimal circuit to run a motor off a battery using a esp32 on wifi. I suppose I could eliminate the charging board for the lifepo4, but I don;t think it makes any difference. I have the esp32 (wemos mini d1, but same happens with nodemcu) serving a web page with faster ...
