Not a smart way to connect Easy Radio modules!
ER900TRS: An extremely smart little module.
You just give it some volts, and a serial string, and it transmits it over air to another ER900TRS. This one can be pretty-pretty far away if you have an antennae - and it willoutput the serial string.
It cannot be more easy to communicate ASCII from one microcontroller to another!
But they are quite expansive, and so I thought instead of usin a new one for each project, I would make some sort of hook-up-system with old IDE-PC-cables..
Idea was that I should just solder the cable, and then insert the module when needed here and there..
This is not a good idea.
Darn thing does not connect very well that way, and so I spend hours and hours bugtracking on the dumb strings that did not come in right :D
Liiiitle looose connections, all the time.
This is how to do it:
I found out that one can just de-solder the pins rom the module, and add some wire. Stick some ffemale headers to the wire, and you are go to insert radio-transmission in 2 minutes on any standard project board :)
