LEW840X, OpenSource Multiple Network Gateways
Bluetooth 5.1, Thread, Zigbee Interfaces
Bluetooth 5.1 module supports Bluetooth 5, Thread, and Zigbee radio interfaces. It also manages LoRa module
LR62E. One of Bluetooth 5.1 modules can be installed.
• BT40F, an nRF5340 module.
• BT40E, an nRF5340 module with an u.FL connector, panel mounted SMA connector for an external antenna.
• BT40X, an nRF52840 module with nRF21540 power amplifier.
• BT40XE, an nRF52840 + nRF21540 module with an u.FL connector, panel mounted SMA connector for an
external antenna.
Nordic nRF5340 SoC has a dual core ARM Cortex
compatible with BT840F series. Firmware configuration of GPIO pins is required.
The application core ARM Cortex
hardware DSP instruction sets. It can handle Bluetooth profiles needing processing power, e.g., BLE 5.1
directional finding, audio.
