Cavli Wireless C16QS LTE CAT 1.bis IoT Module Evaluation Board

Cavli Wireless’ C16QS Smart Module is a low-cost, ultra-low-power, thin-form-factor LTE CAT 1.bis compatible wireless device for IoT applications. Key features include 5 Mbps uplink and 10 Mbps downlink peak network speeds, an integrated eSIM(MMF2), EMEA/APAC/NA region support, and optional high-precision GNSS functionality for GPS/GLONASS/BeiDou/QZSS/Galileo/NavIC constellations.

At the heart of the C16QS is a Qualcomm QCX216 that is based on a low-power ARM Cortex-M3 running at 204 MHz and supported by 4 MB Flash and 1.25 MB RAM. The operating system of the device is FreeRTOS, and standard interfaces include 1x USB 2.0, 4x UART, 2x ADC, and 4x GPIO.

The C16QS features flexible power modes to support long battery life in IoT end devices, with transmit data (TxD) idle mode drawing 10 mA when using 3.7 V supply input (typical within the 2.4 V to 4.2 V range). A normal working temperature of -40°C to +85°C and an extended storage temperature of -50°C to +150°C additionally makes this device suitable for the full range of indoor and outdoor smart home/city, asset tracking, automotive, and manufacturing applications.

There are 12 variants of the C16QS device with different options for coverage, GNSS support, and internal eSIM. These are all contained within a 26.5 x 22.5 x 2.3 mm LGA package.

A development board for this device was released in early 2023, with full stock of market-ready devices now available to support your design.
