<!-- Thanks! for testing out CircuitPython. Now that you have got a problem... you can file a bug report for it. Feel free to modify the below format to better suit your issue. :) --> This arose from an issue on [Discord](https://discord.com/channels/327254708534116352/537365702651150357/833124505504317451). I don't have this board to try it out. **Firmware** <!-- Include the version of CircuitPython you're running. You can see it in the `boot_out.txt` file, as well as in the REPL. --> ```python Adafruit CircuitPython 6.2.0 on 2021-04-05; Adafruit Feather M0 Adalogger with samd21g18 ``` **Code/REPL** <!-- Include your code that reproduces the bug here. Try to distill down to the minimum possible to reproduce. --> In https://github.com/adafruit/Adafruit_CircuitPython_ServoKit library: ```python i2c = board.I2C() ``` **Behavior** <!-- What happens when you run the code above? Include any error messages. --> ```python code.py output: Traceback (most recent call last): File "code.py", line 10, in <module> File "adafruit_servokit.py", line 79, in __init__ ValueError: Invalid pins ``` **Description** <!-- Optionally, describe the issue in more detail. Here are some examples: --> [mpconfigboard.h](https://github.com/adafruit/circuitpython/blob/main/ports/atmel-samd/boards/feather_m0_adalogger/mpconfigboard.h) has SCL on PA22, SDA on PA23 for `DEFAULT_I2C_BUS_` [pins.c](https://github.com/adafruit/circuitpython/blob/main/ports/atmel-samd/boards/feather_m0_adalogger/pins.c) and [schematic](https://learn.adafruit.com/adafruit-feather-m0-adalogger/downloads) have SDA on PA22, SCL on PA23)
