Evaluate size of I2C pullups #4

Closed tmiw closed 2 years ago

tmiw commented 2 years ago

The I2C pullup resistors (R2 and R8) are currently 4.7K. This may be insufficient depending on how fast we drive the I2C bus. Investigate and increase the resistance if necessary.

I2C bus is able to be driven at 100KHz using 4.7K, so keeping as is.
