 This prototype is heavily based on the previous [[prototyping_on_mp2|TPLINK 703N prototype]], but avoids the need for a USB to serial adapter and USB hub. This prototype is heavily based on the previous [[prototyping_on_mp2|TPLINK 703N prototype]], but avoids the need for a USB to serial adapter and USB hub.

   - If you have obtained a normal RFD900, desolder the 16pin header.  Ask RFDesign if they can supply it without the header installed in the first place, as it saves a bit of effort. They may or may not be able to depending on where they are in their manufacturing cycle, but the more people ask, the more they are likely to stock them this way.   - If you have obtained a normal RFD900, desolder the 16pin header.  Ask RFDesign if they can supply it without the header installed in the first place, as it saves a bit of effort.

   - Solder a 4-pin ribbon cable between the MR3020 PCB and RFD900 radio connecting 5v, GND, TX and RX lines appropriately.  See photo for pictorial explanation.    - Solder a 4-pin ribbon cable between the MR3020 PCB and RFD900 radio connecting 5v, GND, TX and RX lines appropriately.  See photo for pictorial explanation.

 +** NOTE: This pinout is wrong. There is no 5V on that header. You need to source it from elsewhere, and there is no really good place. This is one reason we stopped using the MR3020 for prototyping.  If you feed the RFD900 with 3.3v it will seem to work, but your range will be only 1/20th of what it should be. **
