BC840/M/E, Compact BLE 5, Thread, Zigbee Modules Ver 1.00, April 2019 BluNor BC840 is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) using Nordic TM nRF52840 SoC. With an ARM Cortex M4F MCU, available 1MB flash, 256KB RAM, embedded 2.4GHz multi- protocol transceiver, and an integrated PCB trace antenna. It allows faster time to market with reduced development cost. BC840 is an ultra compact(7.0x9.0x1.5mm) and ultra short range (10 meters with an Android phone) module for wearable application. BC832M is compact in size. Its range is measured at 135 meters for 1Mbps data rate. BC840E is an ultra compact (7.0x12x1.8mm) module with ultra long range (3400 meters at 125 Kbps, Low Multiple Path Interference). Per FCC test reports, the peak TX power with ANT060 antenna is +15.38 dBm.
