Good value

Solid board for the price. The pinout diagram could be clearer on the box, but once you find the right schematic online, it works great.

Driver installation tricky

Had to install CP2102 drivers manually on Windows 10. Once that was sorted, the board functions as expected. Just be prepared for setup.

Perfect learning tool

My students love using these for their engineering projects. Dual-core processing handles multitasking well without lag.

5 FAQ

Q: Is it compatible with Arduino IDE?

A: Yes, it is fully compatible. You need to add the ESP32 board manager URL to your preferences and install the ESP32 package.

Q: Can it power external sensors?

A: Yes, it provides 3.3V and 5V output pins. Ensure the total current draw does not exceed the USB source limits.

Q: What is the Bluetooth range?

A: The typical effective range is approximately 10 meters in an open environment, depending on obstacles and interference.

Q: Which USB driver is needed?

A: It depends on the production batch. Most use CP2102, but some use CH340. Please check the chip on your board near the USB port.

Q: Is this board 5V tolerant?

A: No, the GPIO logic level is 3.3V. Connecting 5V directly to GPIO pins may damage the board. Use a logic level converter if needed.
