BLE 5, Thread, Zigbee Modules,BT840X/XEVer 1.11 April 2019

BluNor BT840X is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) using Nordic

nRF52840 SoC. With an ARMCortex

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.
