AR1010 FM Radio Receiver Module

The AR1010 FM Receiver Board is a miniature FM radio receiver whose parameters can be controlled over an I2C ('two-wire') or an SPI ('three-wire') serial interface, thus making it ideal for connection to an Arduino.

The AR1010lib library uses the I2C serial protocol, accessed through the Arduino's analog in pins 4 & 5. It allows for custom initialisation, and the setting of tuning frequency, volume, hardmute and softmute values. Although the library probably isn't feature complete, it shouldn't be difficult to add in higher-level methods using the available programming guide and some of the lower-level methods available in the library.

(The programming guide for the Airoha AR1000 (version 0.81, RevF) is also suitable for the AR1010, and contains accurate register maps of the module's functionality.)

Features:

• 3.3V @ 11mA
• 76-108MHz supported
• 100mV audio output
• Stereo output
