The unit is small and is perfect for use as a HA Bluetooth proxy, the build quality is really good and it connected up instantly. A much easier choice than buy boards and 3d printing cases.

Great little module. Works well with ESPHome. Demo code worked fine, I haven’t put it into production use just yet to measure specific parts like the IR blaster.
