The ISNO Super is an open-hardware ESP32-S3 board carrying two CC1101
sub-GHz radios (433 MHz and 868/915 MHz) combined on a single antenna
through a passive LC diplexer. This environment builds on the
esp32dev-multi_receiver RF stack; it drives the 868/915 MHz radio (868
in the EU, 915 in the US) and parks the 433 MHz one using the existing
RF_MODULE_SECONDARY_CS hook in commonRF.cpp.
