Works but Missing Docs
The board functions well, but I had to search online for a clear pinout diagram. Would be nice to include a link in the package.

Reliable Baseboard
I have bought three of these now. They handle the WiFi current spikes without resetting. Very stable.

Good Quality Board
Solid construction and good pin labeling. The headers were a bit tight for my jumper wires initially but loosened up after use.

Perfect for Prototyping
This board makes using the ESP32 module so much easier. No more messy breadboard wires. Highly recommended for IoT projects.
Q: Is this compatible with the Arduino IDE?
A: Yes, it works standard with the ESP32 Arduino core once the module is installed.
Q: What is the maximum current the 3.3V regulator can supply?
A: The onboard LDO regulator can safely provide up to 500mA for your peripherals.
Q: Does this board come with the ESP32 chip included?
A: No, this is an expansion baseboard only. The ESP32 module needs to be purchased and soldered separately.
Q: What is the pitch of the header pins?
A: The headers use a standard 2.54mm pitch, compatible with most breadboards and Dupont wires.
Q: Can I power this board using a lithium battery?
A: Yes, you can connect a 3.7V Li-ion battery to the VIN and GND pins, but ensure voltage stays within 5V max.
