I2C port on Edge


Are there internal pullup registers for the external I2C on Edge? Or… is the SoC pad configured as pullup? I have a new sensor that I’m testing on ardupilot and it responds correctly on a test board I have, but not on Edge.


Hi, Lucas!

This is missing from our docs but we’ll add it. Thanks for noticing. This port has 10kOhm pull-ups.

Thanks @george.staroselskiy

Is this 10k ohm a physical resistor or a pad configuration one can change in software?

Hi @Lucas_De_Marchi,

It’s a physical resistor.

In regards to docs, we’ve added the information about I2C pull-up resistors in Edge Ports and pinout section.
