AIW designed a breakout board for the Si4707 weather band receiver IC. It features a coax antenna connector, and I2C pins broken out and pulled high to 3.3V. Code sample for interfacing the device to the Arduino was released in the forum.
I do have comms utilizing Arduino I2C bus. The Si4707 is 3.3V so I have the arduino 3.3V output tied to VCC,VIO and to the I2C pull-up resistors. No audio yet because I haven’t bread boarded the audio amp circuit yet, but I am able to do the following: power up, get rev, set frequency, and wb tune status.
