XFW-HX711 80Hz mode

From googling and reading on this forum, I see how the sparkfun HX711 module can be switched from 10Hz to 80Hz by disconnecting a certain pin and connecting it to another.

I have the XFW-HX711 module, which looks like this:

I can't find much information on how to activate 80Hz mode, but the board clearly shows 80 and 10Hz on the board. I assume I need to solder the two pins beside the 80Hz mark (in red in the image). But should I remove the connection by the 10Hz mark (in blue in the image)?

You most likely have to move that zero ohm smd resistor in the blue box to the pads in the red box.

Alternately heat each side of the resistor with a soldering iron until you can sweep of the resistor WITHOUT FORCE.
Then solder it onto the pads in the red box, or bridge the pads in the red box with a blob of solder.

I assume you know that you trade speed for accuracy and/or resolution.
Leo..

Thanks @Wawa! Yes I was assuming there would be a trade off. I have multiple HX711s, so I'll be able to compare the results.

I used this module in my wheelchair design. Pin 15 on the HX711 chip determines the sampling rate. When grounded it samples at 10Hz. When connected to VCC it samples at 80Hz. By default the sampling rate is 10Hz. Meaning it is grounded (with a resistor in the blue box).

To change it to 80Hz you need to connect the pads in the red box AND remove the resistor in the blue box. If you don't remove the resistor you are basically connecting Pin 15 to both ground and VCC, which will short your module.

The noise level is very acceptable and get_units() function in HX711.h can easily damper the noise by averaging specific number of consecutive readings. I think the board should come standard in 80Hz instead.

AFAIK the 10Hz result is equivalent to the average of 8 samples @ 80Hz. If you don't need the speed it saves your processor some effort.
