Finally got my SI4703 board working with a regular Arduino by using a PCA9306 and 4050 to shift the I2C/reset levels. Perhaps future boards could use SPI which is far easier to shift. My understanding is that the chip supports SPI but the design of the breakout board does not(?)
Thanks. I realise that my level shifting with a 4050 won’t work as i2c is bidirectional. I guess I need to find some way of level shifting i2c first.
Do I need to use a logic level shifter if I want to use this board with an Arduino or will it happily accept 5V on the I2C bus? I’m currently using a 4050 to shift to 3.3V but my board is not responding…
What would be the most appropriate way of using a separate antenna and audio amplifier with this breakout board? Would it work reasonably well if I just hooked them up to the jack?
Any chance we could have a breakout board for some DAB digital radio modules such as the Frontier Silicon Venice 7?
In the comments of the example source code there is a request for RDS documentation for the chip - it can be found here:
