Yongnuo RF-603N II N3 for Nikon/Canon modification:

I presently use Camtraptions receivers and transmitters. I like them due to the 3.5 X 1.35 mm DC Power Adapter Jack that they have on the side for plugging in external power to power the transmitter and or receiver for longer durations in the feild.

So I purchased several Yongnuo RF-603N II N3 for Nikon (I use Nikon camera traps) to see if I could add a 3.5 X 1.35 mm DC Power Adapter Jack to them so I could also use external power with them. Another interesting thing with the Yongnuo RF-603N II N3 is that you can set them to be either a receiver or a transmitter via a switch they all have on the side of them. So they can act as a receiver and or a transmitter if you wish.

I know there are others that use these and I would be interested to hear their thoughts on these receivers/transmitters. I will most definitely be testing these with my equipment this spring.

Like I mentioned I use Camtraptions receivers and transmitters. I really like them and have never had an issue with them. The Yongnuo RF-603N II N3 whether Nikon or canon are definitely another option, and are way cheaper.

Lastly the mod is easy to do. I actually was surprised at how easy it was. I drilled a hole to accommodate the 3.5 X 1.35 mm DC Power Adapter Jack plug. I soldered neg and pos wires to the neg and pos battery contact spots as shown in the pics. Then soldered the neg and pos wires to the 3.5 X 1.35 mm DC Power Adapter plug as shown. On the plugs the longer tab is the negative and the shorter tab is the positive. I gooped the outside of the plug since the nut could not be used since the receiver/transmitter housing is thick.

Parts I used:
- Yongnuo RF-603N II N3 for Nikon (you can get for Canon as well)
-3.5 X 1.35 mm DC Power Adapter Jack plug
-DC Power 5.5x2.1mm Male Right Angle to 3.5x1.35mm Male Plug Adapter Cable 1ft. (Purchased of eBay, comes from China) I use this cable to plug from receiver/transmitter and into my external power battery pack.
