BLE 5, Thread, Zigbee Modules, BT840/F/E/X/XE Ver 1.11 May 2019 BluNor BT840F is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) using Nordic TM nRF52840 SoC. With an ARM Cortex M4F MCU, available 1MB flash, 256KB RAM, embedded 2.4GHz multi- protocol transceiver, and an integrated PCB trace antenna or u.FL connector for an external antenna. A power amplifier is integrated in BT840X and BT840XE to increase Bluetooth range. It allows faster time to market with reduced development cost. Bluetooth ranges are measured in environments with Low Multiple Path Interference (LMPI) and antenna at 5 feet (1.52 meters), typical height of thermostat in the USA. Ranges for LMPI, correlating to actual link budget, indicates the Bluetooth signal strength for penetrating walls in buildings.
