Better than ESP8266

The dual-core processing makes a huge difference for multitasking. Deep sleep mode works well for battery projects. Highly recommended.

Good board, driver issues initially

Hardware is solid. Had some trouble installing the USB drivers on Windows 10 at first, but once configured, it runs stable.

Pinout labeling is small

Functionality is fine, but the silk screen printing for the pin numbers is very small and hard to read without a magnifier.
