+This [bellows](https://github.com/zigpy/bellows) radio library for zigpy should be compatible with all EmberZNet based Zigbee radio adapters and modules with a firmware that support EZSP (EmberZNet Serial Protocol).
+
+This tecnically includes the newer EFR32MG24, EFR32MG21/MGM210, EFR32MG13, EFR32MG12/MGM12 from Silicon Labs, as well as Silabs older EM35x/EM35xx (EM357, EM3581, EM3585, EM3587, EM3588) "Ember" family of chips.
+
+Newer series of radio adapters and modules are generally recommended as Silicon Labs still maintains SDK for them so it is possible to get new firmware with bug-fixes and new features.
