When running external wiring to the PCB terminals, keep cable lengths as short as possible to reduce signal degradation. Twisting data wire pairs (such as I2C lines) protects them against external electromagnetic noise generated by nearby AC power supplies or inductive loads like pumps and motors. 4.
