- Apache Mynewt
Blend is very popular as it is a "full-size" Arduino compatible board which supports most shields. It has on board a Cortex-M3 MCU that supports DAPLink, slot for Apple MFi coprocessor and two Grove connectors.
You should choose Blend 2 if you want to test all GPIOs and functions available on the Nordic nRF52832.
