Zigbee OnOff controller

I’ve had them from several places and they all seem to be the same. They use the “RFX2401” amplifier with a non-standard layout.

Zigbee OnOff controller

The programming pads / 5v / 3v3 / Gnd are labeled on the PCB – but do note that the internal power supply isn’t isolating and indeed the 5v supply is at the live mains voltage. Hence if powered by the mains, the entire PCB and all the data lines are at mains voltage and very dangerous.

Attention! They must only be powered by the 5v/3v3 pads whilst programming / out of the case. Do not connect the high voltage wires.

Download the latest version of the configurable firmware here. Then adjust the settings.

Hello, is this module ZHA or ZLL standard? How about after flashing? Thanks for confirmation

Hello,
Thanks for sharing this.
Is it possible to post a picture of the board? Is it easy to connect the programmer to this board?

    Hi Fred,
    it’s easy to open the On/Off controller case. Just use a small screw driver to lift the cover on the back side. The module can then removed from the case. As by ptvo mentioned, the programming pads are labeled on the PCB. I used a small soldering iron to solder Dupont breadboard wires to the required pads, for a connection with the TI CC Debugger. After programming of the cc2530 I desoldered the cables and pluged the module back in his case.

      Thanks Paul
      I just ordered one.
      Are you still happy with yours?
      I hope the range is OK. Since there is an RF front end, it should be good.
      The range of OSRAM smart + plug is just so bad.

Great! Clear description, got it to work within half an hour. On the PCB are also pin P02,P03 and P04 available. Are these I/O’s in use or is it possible to configure them for my own use?
