For the design of the PCB nets I need to know the current consumption of a TFT screen and an SD module. The display microcontroller is the ST7735. In its datasheet I have found the following table:
The current to be aware of is the IDD in the "Maximum" column I imagine. But what is the difference between them? It seems that both "IDDI" and "VDDI" refer to an interface but I don't know what it means exactly.
About the SD module I can't find the data sheet. Does anyone know how much it can consume more or less?
