The FM Transmitter with DIY possibilities
The FM02 is a two board FM transmitter. However, it is not a complete unit ready for use. Instead, it bridges the gap between an out-of-the-box solution, and a build-your-own unit that starts with a bare PCB and a bag of parts.
The FM02 is a very sophisticated assembly. Building a unit of this capability and size would be nearly impossible for most DIY'ers.
So, to create a usable FM transmitter, the FM02 needs some help. The builder of the transmitter will take the FM02 and use it as the corner stone of a complete transmitter.
You will need the following items added to your FM02:
- Power. A regulated 12v DC power supply is needed. 250ma is enough current.
- An Antenna. Never power your unit without an antenna.
- A mounting enclosure. You will need to mount the FM02 boards somewhere safe and dry.

Power Requirements
Do NOT power it up without an antenna. You don't need to have your 'real' antenna ready for this. You can put the adapter on and then stick a 12" piece of wire into the center of the BNC connector. This will dissipate the RF energy just fine. Just be sure you don't enlarge the hole inside the BNC. DO NOT apply anything GREATER then REGULATED 12V DC to your unit. If you aren't sure, then ask for help in the forums. Use a meter to check the voltage first. If all you have is a wall-wart that is labeled 12V, then that is most likely NOT regulated. A simple test of the output voltage with a meter will tell the tale. I use one of the voltage regulators from Sure Electronics with my unit. These are about $5 online.
