nRF52840 board (Nice!Nano clones)

These Chinese Nicenano V2 clones have started popping up on AliExpress. This is great news for us low-power-wireless nerds; As this widens our choice for ready made boards..

Nordic hasn't actually been welcoming towards hobbyists and this has resulted in scarcity of ready-made newbie friendly boards for prototyping (as opposed to esp32 or the ST's bluepill). Which has been a real game stopper for home IOT projects. We've discussed two possible boards in this post. Here is a new viable option.

NRF52840 Development Board Supermini Compatible With Nice!Nano V2.0

Features:

• Mini-sized (breadboard friendly)

• Built-in LiPo battery charger

• Supports charger boost jumper (100mA to 300mA) on the back side

Unfortunately the SWD debug pins are not broken out as headers, but as pads underneath. We'd have to directly solder some wires onto this. I haven't checked them out personally, but they may be shipping with a bootloader for simply flashing purposes.

There is a known issue with higher leak current than the original micro board. This one is reported to have a deep sleep current consumption of 700mA! (reddit)

For more details and the workaround of the issue please follow the link to this site.

As the maker and IoT communities continue to grow, it's exciting to see how this clone will contribute to the world of embedded systems and innovation. Whether you're a seasoned developer or just starting your journey, the Nicenano V2 clone is worth exploring for your next project.
