Overview
KCMCA6S & KCMCA6S-N are sub-GHz WM-Bus modules launched by Quectel, featuring an ARM Cortex-M33 processor with a frequency of up to 78 MHz, and support WM-Bus protocol and comply with the EN 13757 standard, and integrate 32 KB RAM and 256 KB flash.
KCMCA6S series modules are in a LCC form factor with an ultra-compact dimensions of 25.4 mm × 14.0 mm × 2.9 mm, which optimize the size and cost for end-products and are compatible with diverse designs.
KCMCA6S & KCMCA6S-N support multiple WM-Bus communication modes (T, C, S*, R*, N*, F*) and deliver efficient transmission through a low-power architecture, dynamic multi-mode switching, and flexible frequency configuration, alongside integrated multi-layer security mechanisms. As a widely adopted standard in Europe for smart metering, they are ideal for smart water/electricity/gas/heat meters and AMI (advanced metering infrastructure) systems, while also demonstrating strong potential in IoT connectivity scenarios.
