rboard - Cheap relay/radio/arduino board ~$10
-
I realise quite a few are building your own PCB's and i admit i really enjoyed the process of designing and producing my first "mysensors" pcb ... but when you find prebuild boards like this for such little money then its hard to ignore...
So i bought 2 of these today
http://imall.iteadstudio.com/im140704001.htmlI plan to use one for my garage door controller...the other not sure yet ;-)
-
Nice find. Please let us now how they perform.
-
Finally got the email they are on the way....will report in when ive tested them,
-
And they just arrived... 6days ..not too bad!
Now to test!
-
Well that was easy....
Loaded up the RelayActuator sketch, changed the relay pin to 4.
It joined Vera as it should, and after providing it a 5V powersource the relay clicks on and off as commanded! -
Now loaded up the Garage Door sketch , choosing A0 for the switch and D4 for the relay and again works straight away!
I note they also have a header for 433Mhz module and according to the schematic, the pads could be used for 5v,GND, and D3 - so could be used for another sensor such as Dallas temp....or ultrasonic/IR..anything!
Great buy for $10

Good price but a pity you still need an external 5 Volts supply...
-
Yep no getting away from the need for power! A mains version would be great, but although it only adds a few $ in electronics, getting all the approvals adds $$$. But for DIY'ers adding a phone powersupply is cheap and reasonably compact.

Yeah it seems like a really nice board but it could have had access to a few more digital pins on the board.
Is it really only A0 and D3 that can be accessed other then the relay? -
