+ | =====Functional Description ===== | ||
+ | The %%Pmod RJ45%% utilizes the traces on RJ45 cables (Ethernet cables) to transmit signals through the cable to the other side. Although the cables are typically used for Ethernet, the data lines can also be used as general purpose inputs and/or outputs as they are essentially just wires. The benefit is to be able to use a widely used shielded cable that nicely contains and conceals all of the data and power wires. | ||

+ | ===== Physical Dimensions ===== | ||
+ | The pins on the pin header are spaced 100 mil apart. The PCB is 1.375 inches long on the sides parallel to the pins on the pin header and 0.8 inches long on the sides perpendicular to the pin header. | ||
