# Makerdiary nRF52840 M.2 Developer Kit
2+
3+
The devkit is a versatile IoT prototyping platform,
4+
including the nRF52840 M.2 Module and M.2 Dock. You can use the developer kit
5+
to prototype your IoT products and then scale to production faster using the
6+
nRF52840 M.2 Module combined with your custom PCB hardware.
7+
8+
Refer to https://github.com/makerdiary/nrf52840-m2-devkit for more details.
