Bluetooth 5, Thread, Zigbee Interfaces!
Bluetooth 5 module supports Bluetooth 5, Thread, and Zigbee radio interfaces. It also manages LoRa module
LR62E. One of four Bluetooth 5 modules can be installed.
• BT840F, an nRF52840 module. It is FCC certified with max. TX power of +8.46 dBm.
• BT840E, an nRF52840 module with an u.FL connector, panel mounted SMA connector for an external
antenna. It passes FCC certification testing with ANT060, a 6 dBi antenna.
• BT840X, an nRF52840 module with SKY66112 power amplifier. It passes FCC testings at +21 dBm TX.
• BT840XE, an nRF52840 + SKY66112 module with an u.FL connector, panel mounted SMA connector for an
external antenna. It passes FCC testings with ANT000, a 0 dBi antenna.
Maximum TX power of BT840X is about 13.8 dB higher than that of BT840F. The receiver gain of SKY66112 is
measured at 1.5 dB. Comparing to BT840F, BT840X has 15 dB more link budget. In
free space (antenna high above ground and without obstruction), 15 dB link budget
can more than quadruple range. Or, it is enough to penetrate 2 dry walls in typical
house in the U.S.A.
If you are developing a mesh network or sensor using BT840X/XE, a gateway with
BT840X/XE will provide the longest possible Bluetooth, Thread or Zigbee range.
If this gateway is to receive data from various (Fanstel and non Fanstel) sensors, beacons, BT840E with
ANT060 antenna will provide the best receiver sensitivity if antennas are deployed in parallel (horizontal
polarization).
