Easy to Solder and Use
The castellated holes make soldering headers very easy. I use this with PlatformIO and Arduino IDE without any issues. Great value for the price point.

Perfect Size for Wearables
I needed something small for a wearable project and this fits perfectly. The solderable pads are well spaced. Battery life is decent with deep sleep modes enabled.
