Good value board

Wi-Fi range is decent for the price. Documentation could be slightly better for absolute beginners, but plenty of online resources exist.

Perfect ESP32 clone

Fast shipping and well packaged. All pins are accessible and the voltage regulator handles 5V input without overheating.

Solid beginner board

Pin headers were not soldered which was fine for me, but note that if you want plug-and-play. Performance is excellent.
