There is an optional board param than may be passed in the constructor opts for all device classes. Simply put, it allows the user to specify which board they want to use in projects that have multiple boards. It is currently not documented anywhere and should probably be added to all the classes.

I'm trying to use this library to receive signals with generic 433mhz receiver (sender is a door sensor operating on the same freq). it seems like set_async_interrupt runs a lambda on another thread and will reset interrupt handler back to none, so that next interrupt doesnt trigger any lambda.

However radio receiver will trigger many interrupts, so I was wondering if you could provide a us

Can you mention channel configuration? It doesn't seem to be TAER, since you mention channel 3 as throttle, so what do we need to set the radio to?
