If you have a custom PCB design and you'd like to add a little Bluetooth Low Energy, this module is ultra compact and easy to use. It contains a Nordic nRF52832 chip that comes integrated with BLE radio as well as most of the supporting circuitry and even a chip antenna. The whole thing comes with FCC, CE and TELEC certifications.
Please note! The module comes with a blank chip - this is for people who are comfortable programming the chips themselves with a J-Link programmer and the Nordic SDK. We don't provide any firmware to go along with it!
This is the same module we use for the Adafruit nRF52832 Feather so if you'd like to see a possible reference design for this module, check out the PCB files here!
Of course the best way to program these chips is with the Nordic SDK. This chip also has some basic Arduino support, some micropython support, and is well supported by MyNewt. Either way you go (SDK/micropython/Arduino) you'll still need to solder this onto a PCB and load code via a SWD programmer.
