Hi all,

I’ve been searching for documentation on the **Dephy Load Cell Amplifier Board** , but haven’t had any luck so far. Do you happen to have access to the schematics or a datasheet? Either one would be pretty helpful.

My main question is whether the board includes **pull-up resistors** on the I2C communication lines (SCK, SDA).

Thanks in advance!

Hey Axel,

The SCK and SDA lines have 1.8 kohm pull-up resistors
