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 Cortex M4 chip that comes integrated with BLE radio, USB as well as most of the supporting circuitry and even a chip antenna. The whole thing is in a tin and comes with FCC, CE and TELEC certifications.
This chip is quite a beast, with a ton of FLASH, SRAM, peripherals and best of all … native USB support! No need for an external USB-serial converter chip. However, given that it uses under-pads instead of castellated pads, you cannot hand-solder it, you’ll need a stencil and hot air or a reflow oven.
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!
Of course the best way to program these chips is with the Nordic SDK. This chip also has some basic Arduino support, CircuitPython support, and is supported by MyNewt. Either way you go (SDK/CircuitPython/Arduino) you’ll still need to solder this onto a PCB and load code via a SWD programmer.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
