Bluetooth 5 Modules with Amplifier, BT832X and BT832XE Ver 2.01 June 2018 BluNor BT832X is a powerful, highly flexible, Bluetooth Low Energy (BLE) using TM Nordic nRF52832 SoC. With an ARM Cortex M4F MCU, available 512KB flash, 64KB RAM, embedded 2.4GHz multi-protocol transceiver, power amplifier, and an integrated PCB trace antenna, or an u.FL connector for external antenna. It allows faster time to market with reduced development cost. For applications needing limited number of IO pins, prototyping and production are easier using 16 castellated pins. Additional 24 LGA (Land Grid Array) pins provide access to 29 GPIOs of nRF52832. Line of sight range between 2 BT832X is 1170 meters. Ranges between 2 BT832XE with ANT060 external antenna is 1350 meters. Specications: Nordic nRF52832 with ARM Cortex M4F.
