OOK 433 Plug (discontinued)

The OOK 433 Plug is a small board which allows communication to and from wireless devices using 433 MHz with On-Off Keying, as used by many low cost weather sensors, wireless power switches, etc.


There is one solder jumper which determines whether the transmitter and receiver are powered from the PWR line or from the +3V line - this should normally be set to +3V (solder on *rightmost two pads in picture below).
There is another solder jumper which needs to be closed when the R1 resistor is not present (bottom left in picture below). This could be used to limit current of the output pin when the receiver is operated at a higher voltage than the logic levels.

The 4-pin version of the transmitter needs to be mounted differently! See the OOK fix mentioned below.*
h2. Design Info
Dimensions: 21.1 x 24.1 mm
CadSoft EAGLE design files: see below.
This plug can be operated at 5V as well as 3.3V.
This board uses the conventions of a JeePlug and can be used with the ports on a JeeNode. It can also be used with other boards and MCU’s, if you hook it up properly and adapt the interface code for it.
