Hi

Does anyone have a source of data sheets and/or instructions for the KEYES modules available through DX or Cutedigi?

Cutedigi and a couple of other sites have some info but most are very light on detail

Thanks

Thanks DC

I'll give it a go and see what I end up with

Hi

It is a LM393.

7 of the modules in the kit have the same board. They all differ from the ones in the cutedigi kit in that these are all Red and have 4 pins labelled A0, G, + & D0.

They are Keyes Modules but I can not find any datasheets on any Keyes boards anywhere.

Thanks

Hi
I am an Arduino newbee and have a Sensor set from DX.

I am trying to work my way through all the sensors but I can not find any example code for the KY028 (4 pin) Temperature module.

It looks like this

Any help gratefully accepted.
