Title: Short chinese translation help needed
Post by: martonmiklos on October 03, 2021, 07:22:29 pm

Hello folks,

Would someone who is  fluent in chinese be so kind to translate the pinout from the attached picture.

The resolution is so bad that I have not managed to OCR it with any online service :(

Dude, just press the button on your phone, press "translate" and point the camera at the thing.

They may not have a smartphone, not all do. :)

Many thanks, I am using Sailfish OS which does not have such a capability.
Anyway it is amazing to see that the built Android/ios OCR+translation works better than the online services.

Just for future reference it is the pinout of a toy car controller called Weelye RX16 6V

1: NC
2: forward switch (active low, pulled up to the 3V MCU power internally)
3: reverse switch (active low, pulled up to the 3V MCU power internally)
4: GND
5: Manual/remote controlled operation
6: 6V for the MCU LDO
7: 6V for the relays

To feed the wisdom of the internet further (in the case if you coming to this page with repair intentions):
If some of the relays seems to be activated unintentionally during power up and turning on and off over time randomly:
Check the voltage on the forward/reverse switches.
In my case the internal pull up got dead in the MCU (which marking is sanded off...) or something inside started to pulling the line low with some sub KOhm pull.
Adding a 330 Ohm external pullup seems to be solving the problem.
