Perfect for wearables
Low power consumption makes this ideal for battery-powered wearable prototypes. The ceramic antenna saves space.

Great little board for IoT
Works perfectly for my sensor node projects. The OLED screen is small but crisp enough for status messages. WiFi connection is stable.

Good value, tiny screen
The board itself is excellent and easy to program. Just be aware the display is very small, so don't expect to show graphs.

Decent hardware, unclear pinout
Hardware works well but I had to dig around for a clear pinout diagram. Once figured out, it performs as expected.
