Add pullup resistors to the I2C signals #39

Closed macphyter closed 5 months ago

macphyter commented 5 months ago

It appears that the I2C signals from the ESP32 might already have pullups, but they are extremely weak. We should add our own pullups because the I2C signal goes across the entire board from end to end. Also, the PMBus spec calls out stronger pullups.

Added to v304 schematic, still needs to be added to PCB layout.

Finished I2C pullup resistors on PCB layout Fixed on v304
