Excellent ESP32 Clone

Pinout matches the standard D1 layout. Wi-Fi range is surprisingly good for the size.

Decent but runs warm

Functions well but gets warm during heavy Wi-Fi usage. Make sure to provide ventilation.

Good value but driver needed

Board works great once I installed the CP2102 drivers. Compact size fits well in my enclosures.
