I mean that how much it takes current alone, for test purposes. Let me elaborate:
As I mentioned, I broke my throttle controller, hub PCB and the voltage converter.
I removed the voltage converter and measured the output with input connected to 50 volts: output was 0 volts.
Then I connected the hub PCB with throttle controller connected to it (but not the ESCs) to a power source and measured the current that it takes. It took way over an ampere total
Then I connected the hub PCB alone (i.e. nothing else connected to it) to power source and measured the current that it takes. It took 220mA at 5 volts. Green led was blinking and red power led was on, so it seemed to be alive. But the current seems a lot to me so I am wondering how much it usually should take. It may be broken as well.
And finally I measured the throttle controller PCB resistance between 5V and GND, and it was practically shortcutted. I measured throughout the board, and both the MCU and the motor driver circuit was shortcutted. I removed them and it seems to have fixed the shortcut problem. So now I am wondering if only that throttle PCB was broken or if the hub board is also broken.
And also I am trying to find replacement components to the throttle PCB, but it seems that the MCU is very difficult to get. The lead times are 82 weeks. Don’t know what to do with that.
