Base Dock
Grove compatible dock for building rapidly IoT applications with nRF52832-MDK or nRF52840-MDK


The Base Dock is an essential tool allowing you to build rapidly Internet of Things applications. It is an ideal add-on to the existing nRF52832-MDK and nRF52840-MDK development boards.

The Base Dock can be powered by only one AA battery, and it also features a power button and a PCB NFC antenna. It is also Grove compatible, which means you can connect easily and quickly sensors with the 4 Grove connectors.
