BLE SiP Module


The MtM+ M905 is the smallest Bluetooth low energy (BLE) SiP module with a built-in antenna. It is an ARM® Cortex™-M4F 32bit based processor and is designed for Bluetooth® Smart and IoT solutions.

Low power consumption

7.5mA when TX at +4dBm output power.

NFC touch to pair

Also with hardware divider, FPU and DAC



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.


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.
