BLE 5, Thread, Zigbee Modules,BT840X/XE
BluNor BT840X is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) using Nordic
nRF52840 SoC. With an ARMCortex
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.
