Datasheet

also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly
battery (https://adafru.it/e0v) and MicroUSB cable (https://adafru.it/aM5) not included (but we do have lots of options
in the shop if you'd like!)
Bluetooth Certification Warning
Because of complex and expensive Bluetooth SIG certification requirements, the nRF52 Pro doesn't ship with any
default Bluetooth functionality on the post-production firmware, since at present the Mynewt BLE stack has not gone
through the certification process with the Bluetooth SIG. We aren't able to ship BLE functionality out of the box without
this certification. In order to use Mynewt in a production product, you will need to go through the certification process
for your product, although you are free to develop locally with Mynewt in a test environment.
The only Bluetooth Low Energy stack certified to run on the nRF52 modules with no additional work on your part is the
Nordic SoftDevice, which is used in the Arduino variant of these boards and can be flashed onto the nRF52 Pro using
your choice of ARM SWD debugger, such as the Segger J-Link. (https://adafru.it/yDp)
When the Mynewt stack is certified by the Bluetooth SIG (no ETA on if or when that will happen since it's a long and
expensive process), Bluetooth functionality will be enabled on shipping devices, but at present only USB Serial is used
in the default firmware on production devices, and the Nordic SD should be used in commercial products if you are not
able to go through the certification process yourself. There are no HW restrictions on the nRF52 Pro boards, we simply
have our hands tied on what we can ship and claim coming off the production line.
UPDATE (Sept 17 2017): Runtime, one of the main contributors to the Mynewt core codebase, have contracted
an external company to certify nimble (the Mynewt BLE stack). Once the certification process is completed,
the results and certificate details will be posted here.
