FLC-BTM020 uses the 32-bit ARM Cortex M4F MCU, base of NRF52832, together with extensive flash availability, 512kB in total.

This module enables customers to add ultra-low power wireless connectivity to their products. Customers can easily establish wireless connections with the module. It supports Bluetooth low energy (Bluetooth 5), ANT and 2.4GHz proprietary protocol stacks. It also has a NFC-A tag interface for OOB pairing.

Bluetooth low energy takes less time to establish a connection than conventional Bluetooth wireless technology and can consume approximately 1/20th of the power of Bluetooth Basic Rate. BTM020 Used in smart home, health care, smart wearable equipment, etc.
