Earlier this year, I reviewed the Phottix Cleon II. It's a wireless shutter release that operates on 433MHz, with a range of upto 100m, and uses a smart-code system with 16,000,000 combinations instead of DIP switches to set the channel.

Instead of the camera cable being hard-wired into the receiver, Phottix use a 3.5mm stereo socket on the receiver, and Phottix make cables to suit various cameras. This allows a Phottix Cleon II to be used with different types of cameras, providing you have cables available to suit the different cameras.

Refer to my review of the Cleon II for more details on functionality and features.

I was interested in taking a closer look at the circuitry inside the Cleon II, and after noticing something rattling inside the receiver, I decided to open up the Cleon II.

Here are the Cleon II transmitter and receiver before disassembly:
