Quectel has introduced the KCMCA6S sequence of Wi-fi M‑Bus (WM‑Bus) modules, able to sub-1 GHz operation for sensible metering. Based mostly on Silicon Labs’ EFR32FG23 wi-fi SoC, that includes a 73‑MHz Arm Cortex‑M33 processor, the modules function within the 868‑MHz, 433‑MHz, and 169‑MHz bands.
The gadgets adjust to EN 13757‑4, the European customary for wi-fi metering, and assist the WM‑Bus protocol and different proprietary sub‑GHz protocols. Their built-in software program stack and versatile configuration modes remove the necessity for third-party protocol integration.
Modules embody an non-compulsory built-in SAW filter to restrict interference from mobile indicators, an necessary issue for gadgets combining WM-Bus with mobile applied sciences equivalent to NB-IoT or LTE Cat 1. They characteristic 32 KB of RAM and 256 KB of flash reminiscence.
Availability for the KCMCA6S sequence was not supplied on the time of this announcement.
The put up WM-Bus modules allow versatile sub-GHz metering appeared first on EDN.
