I am looking to connect a Pmod HYGRO module to an RPi 3B through a Pmod HAT. The Pmod HYGRO uses the I2C protocol, and I understand that this requires pull-up resistors on the SCL/SDA lines. However, from what I've read, the RPi has built in resistors to handle this, and I'm wondering when I would use the pull-up jumpers on the Pmod HAT?
