BT840 nRF52840 BLE 5 Modules

Fanstel BT840 nRF52840 BLE 5 Modules are an advanced, highly flexible solution for demanding ultralow power, ultralong 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 u.FL connector for external antenna. BT840F uses a superior PCB trace antenna, proofed in the BT832F module to have the longest range at +4dBm transmission power at a 1Mbps data rate.
