1. PLL FM Stereo Radio(Receiver) Unit.
* This is a miniature-sized receiver that can pick up wireless signals/FM broadcast
signals over 76-108MHz, having same functions as FM Radio set(Radio & Receiver).
* While generally used receivers work on a single or several pre-determined frequencies,
NR-B108RU can pick up any stereo signals of any frequency within the range of 76-108MHz.
* Miniature-sized to fit into any of your products, it is especially easy to install in electronic
devices of compact size.
* You can set receive frequencies on 4 switches. ex) 82.6MHz .....set on 0, 8, 2 or 6.
* You can set frequencies from MCU as well.
Set frequency select switch on 0000. ---> Transmit as serial data 082.6M (9600,8,1,N).

*** How to input frequencies as serial from CPU(MCU) ***
1. Set the frequency on "0000" when controlling from MCU.
2. Transmit to MCU control terminal as Serial Data (TTL level).
ex) Receive frequency 82.6MHz............Transmit "082.6M" from UART-Port TTL Level
. Please use the NR-B108 Only Antenna (PN-ANT-FM) or FM Frequency Antenna.
. Use DC 5V for power (VCC)
. For bigger sound, connect Audio AMP to R-OUT or L-OUT (use audio amplifier or LM386).
