Good hardware, docs lacking
Board works well but finding specific pinout info took time. Hardware quality is solid for the price point.

Perfect for IoT projects
Works flawlessly with Arduino IDE. The small form factor is a huge plus for compact designs. Wi-Fi connection is stable.

Low power consumption
Battery life is impressive on Bluetooth LE projects. Deep sleep modes work as expected. Highly recommend for battery projects.
