Low power consumption

7.5mA when TX at +4dBm output power.

NFC touch to pair

Also with hardware divider, FPU and DAC

5.0

Bluetooth

Increase speed and reliability of data transfer between BLE devices. Specifically for IoT application.

Built-in Antenna

The antenna is built on SiP package.
No extra space is needed for your design.

Audio

Capable for digital microphone and voice input speech recognition control.

Bluetooth Mesh

The addition of mesh networking capabilities to Bluetooth Low Energy enables extended range, increases the number of nodes and a many-to-many (m:m) communication topology.
