an SWD connector and an additional DFU button. If you want to use the nRF52 with Arduino IDE please check out the

Bluefruit nRF52 Feather which works out-of-the-box with our Arduino board support package. (https://adafru.it/vAx)

This Feather is for advanced users only, you will be interacting with the Mynewt RTOS rather than Arduino and you

cannot easily go back-and-forth without an SWD programmer.

This chip has twice the flash, SRAM and performance of the earlier nRF51-based modules, and can do a lot of heavy

lifting. That extra processing power and memory means you can now run an RTOS for fast development of complex

projects. This board was designed to work with the Apache Mynewt (https://adafru.it/yua) operating system, which is

released by the Apache Foundation under the permissive and commercial-friendly Apache license. Apache Mynewt

includes a number of professionally written networking stacks (BLE 5.0, OIC/OCF (https://adafru.it/yub), etc.),

development tools, and professional project management features like a secure bootloader that allows you to

cryptographically sign firmware images and verify them during device updates.
