I’m trying to make sense of the I2C power supply in the schematic. I have two questions, both on Sheet 10:
For the life of me, I can’t find a power supply that supplies VCC_I2C_M. Is there a jumper I’m missing?
Related to #1, there’s a definite error on the schematic. R464 and R465 are zero-ohm resistors that connect VCC_1V8 and VCC_3V3 together as well as directly connecting them to VCC_I2C_M. At least one of those has to be a DNI or the board would catch fire, which it clearly doesn’t. So I’m wondering which (or neither?) is connected?
