Hey Folks,
I would like to use more than two NS73M FM transmitters on one Arduino I2C bus, but from what I gather from the documentation, each device has an address of 110011x, where x is a bit set by pulling the LA pin up or down. This results in only 2 unique addresses. Does anyone know how I might add more than two of these devices on the I2C bus?
Thanks!

The NS73M allows you to select one of two address pairs by way of the LA pin (1100110x and 1100111x where x is 0 for write and 1 for read). Although I haven’t tried it, that implies that you could have two NS73M’s on the bus. I do know that the addressing works.
BTW this will likely violate all FCC rules… That aside, why would you want to do this? You could of course use the SPI mode instead, and use multiple latch enable pins, one for each NS73M.
