BT840 nRF52840 BLE 5 Modules

Fanstel BT840 nRF52840 BLE 5 Modules are an advanced, highly flexible solution for demanding ultra-low power, ultra-long range, and higher throughput applications for IoT applications. A cryptographic accelerator is embedded for industry-grade security. BT840 is a low cost, small size, short range alternative to the BT840F. Both have identical soldering pad footprints. BT840E is a sister module with an u.FL connector for external antenna. BT840F uses a superior PCB trace antenna which in the BT832F module proved to have the longest range at +4dBm of transmission power at a data rate of 1Mbps.
