Bluetooth FM Transmitters

There are two main types of Bluetooth FM transmitters: those that plug into the cigarette lighter port, and those that plug into the stereo’s aux input. 

The first type of Bluetooth FM transmitter is the kind that plugs into your vehicle’s cigarette lighter port. These devices typically have a small display where you can see the current radio station frequency. They also usually have a couple of buttons so that you can change the radio station. Some of these devices also come with a USB port so that you can charge your phone while you’re using the transmitter. 

The second type of Bluetooth FM transmitter is the kind that plugs into your car stereo’s aux input. These devices don’t usually have a display, but they will have controls so that you can change the radio station. These types of transmitters are typically less expensive than the ones that plug into the cigarette lighter port.

  1. How modern transmitter are made

The vast majority of Bluetooth FM transmitters are made using surface-mount technology (SMT). SMT is a method for making electronic components and printed circuit boards (PCBs) in which the components are mounted or placed on the surface of the board rather than through holes.

This type of manufacturing is much faster and cheaper than the alternative, through-hole technology (THT), in which components are inserted into holes in the PCB. SMT also allows for a much higher density of components, meaning that more can be fit onto a smaller board.

Bluetooth FM transmitters generally consist of a few key components: an antenna, a radio module, and a control chip. The antenna is used to receive and transmitting radio signals, while the radio module converts those signals into audio that can be played over your car’s speakers.

The control chip is responsible for managing all of the other components and ensuring that they work together properly. It’s this chip that handles tasks like pairing with your phone, changing the frequency, and displaying information on the screen.
