Documentation could be better
Hardware is fine but finding specific pinout diagrams took some searching online.

Excellent Wi-Fi Stability
I have deployed ten of these and the connection stability is superior to older ESP8266 models.

Good but needs adapter
Works great with Arduino IDE. Just note that the pin spacing is tight for standard breadboards.

Compact and Powerful
This board is incredibly small yet packs all the features I need for my home automation sensors.
Q: Can I power this directly with 3.3V?
A: Yes, you can bypass the regulator by supplying 3.3V to the designated 3V3 pin.
Q: Does this version have an external antenna connector?
A: No, the SuperMini version utilizes a built-in PCB antenna only.
Q: What is the maximum current per GPIO pin?
A: Each GPIO pin can safely source or sink up to 40mA of current.
Q: Is this compatible with the Arduino IDE?
A: Yes, this board is fully supported via the ESP32 board manager package in Arduino IDE.
Q: Is the USB-C port for data or power only?
A: The USB-C port supports both data transfer for programming and power delivery.
