Quectel’s KCMA32S Zigbee/BLE module combines a compact design with versatile connectivity for a variety of IoT gadgets. It’s constructed on Silicon Labs’ ultra-low-power EFR32MG21 wi-fi SoC, which integrates an Arm Cortex-M33 processor working at as much as 80 MHz and helps Zigbee 3.0 and BLE 5.3 for concurrent protocol operation.
The KCMA32S allows mesh networking over Zigbee and BLE, supporting scalable, many-to-many communication for sensible lighting, constructing automation, and residential networks. An non-compulsory Safe Vault function provides superior safety, whereas versatile reminiscence configurations—as much as 96 KB of SRAM and 1024 KB of flash—supply ample headroom for software improvement.
With its small-scale 20×12×2.2-mm LCC+LGA type issue, the KCMA32S helps scale back each dimension and price in finish merchandise. It affords as much as 20 GPIOs, multiplexable by way of the QuecOpen SDK for interfaces comparable to I²C, UART, SPI, and I²S. The module delivers a obtain sensitivity of –104 dBm and transmit energy as much as +20 dBm, with non-compulsory PCB antenna, RF coaxial connector, or pin antenna interfaces.
A timeline for availability of the KCMA32S Zigbee/BLE module was not offered on the time of this announcement.
