M.2 Dock
An essential carrier board to quickly prototype your next embedded design with a removable M.2 module.


The M.2 Dock is an essential carrier board to quickly prototype your next embedded design with a removable M.2 module. It features a fully-integrated DAPLink debugger with Power Profiling, enabling you to program, debug and perform real-time current profiling of your IoT applications without using external tools.

This design extends the interfaces compared to the M.2 Module through an M.2 E-Key connector, including USB 2.0 ports, UART, SPI, TWI, PDM, I2S, PWM, ADC and GPIOs.

The M.2 Dock also comes with 1.3" 240x240 Color IPS TFT LCD, Li-Po Battery Charger, microSD Card Slot, Grove Connectors, LEDs and Buttons.

Supported Modules

The following shows the M.2 module that can work with M.2 Dock. More modules are planned and will show up gradually over time.


We think the best way to learn is by doing. And to help you get started, we have provided a series of tutorials. Find the details below:

We also offer the nRF52840 M.2 Developer Kit to help you prototype your application and then scale to production faster using the nRF52840 M.2 Module combined with your custom PCB hardware.
