Thank you, @neo_95.Are you referring to all of the pins that I asked about, or just some of them?@RegisHsu

Hi RegisHsu!This is an amazing project.I am having trouble corresponding the schematic to the pictures and instructions.What are I2C_J1, I2C_J2, JP1-4, and the connector with pins 1 & 2? (see images)You also refer to pins A4 and A5 on the mini Pro, but I do not see those pins.Thank you very much for your reply!
