hi everybody .. hope you are doing well
i am working with the HX711 module as you can see in the picture attached, and i know that the chip has two speeds 10Hz when pin 15=0 and 80Hz when pin15 =1 as specified in its data sheet. however i would like to know if there is another way to get pin 15 to be 1 other than lifting it and connecting it to vcc. i also would like to know if pin 15 is connected to 10 Hz or the 1Hz was just on its way.
data sheet
It looks like there is an unpopulated set of pads there. There is a resistor close by . Can you do a continuity check with a meter to see if that resistor is connected to the RATE pin-15 on one side and GND on the other and then see if the unpopulated set of pads is connected to pin-15 on one pad and Vcc (5V) on the other pad ? If so, it means all you have to do is remove the resistor from where it is and solder it to the other set of pads to "pull up " pin-15. It would not make sense for the manufacturer (designer ) of that PCB to require an enduser to "lift a pin" on an IC. I can't see that happening. The vendor might be able to help.
Yes, I think you just move the 0 ohm resistor to the 80Hz pads - hot air rework station is the safest
way to do this, but its doable with care by hand soldering.
We do it with two soldering irons at work.
We had a tweezer adaptor for the METCAL station but I don't know if it still works.
