vices, systems, and sensors communicating with high data rates or over a long distance. The 2.4 GHz modules support long-range Time-of-Flight (ToF) distance measurement for indoor and out-
door localization down to an accuracy of 5 meters. Power consumption can be optimized to run from a small-sized battery. The integrated ARM Cortex-M0+ or M4 32-bit microcontroller runs entire RF stacks and has sufficient resources to run user applications. 32.768 kHz 52 MHz Figure 1: Block diagram FMLR-8X-X-STX The modules are available with additional onboard flash memory to enable Over-the-Air (OTA) update and data storage. The FMLR family supports additional modulation schemes like the very efficient and robust high-bitrate and long-range FLRC. This enables communication with smart-
phones, tablets, gadgets, and more. Optional low-power high precision temperature compen-
sated oscillators (TCXO) for both RTC and radio available. The module's firmware, including the wireless stack, can be updated via SWD, UART-Bootloader or OTA, to support fast prototyping and development. FMLR-8X-X-STX 3/14 Ext.
