Introduction

BluNor BT840F is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) using Nordic nRF52840 SoC. With an ARM CortexTM M4F MCU, available 1MB flash, 256KB RAM, embedded 2.4GHz multiprotocol transceiver, and an integrated PCB trace antenna or u.FL connector for an external antenna. A power amplifier is integrated in BT840X and BT840XE to increase Bluetooth range. It allows faster time to market with reduced development cost. BluNor BT840F Series are powerful, highly flexible, ultra low power wireless modules using Nordic nRF52840 SoCs. With an ARM CortexTM M4F MCU, 1MB flash, 256KB RAM, embedded 2.4GHz multi - protocol transceiver, and an integrated antenna, it allows faster time to market with reduced development cost. The following is a block diagram of BT840F. Antenna circuit and main clock are integrated. All 48 GPIOs of nRF52840 can be accessed from main board. For lower power consumption at idle state, a 32.768 kHz crystal can be added on the host board. Connection to an external NFC (Near Field Communication) antenna is provided. BlurNor BT840F is a sister module of BT832F. The physical size is the same. There are 21 additional LGA pins for additional GPIOs provided by nRF52840. There are 3 modules in the BT840F Series. BT840F uses an nRF52840 QIAA with Cortex M4F MCU 1MB flash, 256 KB RAM Supports NFC Integrated PCB trace range antenna. Bluetooth range is 1000 meters at 1Mbps and 2300 meters at 125 Kbps measured in environments with low RF and multiple path interferences. Size: 15x20.8x1.9mm.
