The Badger'd nRFNANO is an Arduino ProMicro form factor
nrf52840 development board.
nRFNANO comes with fully compatible pinout with nice!nano. In addition to that you will have an exposed
pad to add extra safety for your charging circuit which allows you to connect a temperature sensor.
It comes with UF2 drag and drop bootloader which makes life way much easier for developers. With extra
isolated PCB antenna, it will provide relatively powerful signal which allows more stable connections
when there are obstacles in between.

Frequently Asked Questions
Where can I find the example application that the board came with?
We are publishing some of the materials we use during development of nRFNANO in this github repo. You can find the example applications in the repository.
How can I put nRFNANO into bootloader mode?
To activate UF2 bootloader simply double tap nRESET pin. You can use a pair of tweezers to connect nRESET and GND pins of the board twice, this will activate bootloader mode so that you can reflash the UF2 firmware you have.
Where can I find the original UF2 firmware for nRFNANO?
nRFNANO has compatible hardware design and pinout with nice!nano so the firmwares compatible with nice!nano
should work with nRFNANO as well. But if you want to download the firmware we ship, you can get it from
here.

Is there a specific connector for debug pins?
Yes, footprint of the debug pins are compatible with Tag-Connect cables, we used TC2030-CTX-NL footprint to prevent cable mess and speed-up the debugging/testing of the boards.
