Turn on/off each mcp port or all module

[Haysar2019]

Hi, this is a question, as I said with Christopher. I would like to know if is possible control the mcp module, example, turn on/off the whole module or turn on/off each A/D port? I'm using the MCP3008 module, but actually I'm using only 3 sensors connected on mcp3008 and I would like to send power only for these sensors and not for all ports and send the power only I need and not all time. I need this have more control about on mcp 3008 module to reduce battery consumption. Thanks, Haysar Lelis

Hi there, according to the data sheet, you can't turn individual ports on and off. So if you want to use less current, then you should just use a smaller module -- e.g. it sounds like the MCP3004 would be a better fit for your design.

That said, the chip already goes into low-power mode between reads, because when the CS pin goes high, it goes into standby mode (which this addon already does).
