Perfect for IoT projects
This board works flawlessly with the Arduino IDE. The CH340C driver installed easily on Windows 11, and I was uploading code within minutes. Great value for the price.

Great for learning
As someone new to embedded systems, this board was easy to set up. Plenty of tutorials online work directly with this hardware. Only wish it came with header pins pre-soldered.

Best upgrade from ESP8266
Switching from the ESP8266 to this ESP32E version was seamless. The added Bluetooth functionality and extra GPIOs make it much more versatile for my home automation setup.

Solid build quality
The PCB looks clean and the components are well-soldered. I've been running it continuously for a week monitoring temperature and humidity without any crashes.

Good board, minor pin labeling issue
The performance is excellent and WiFi range is solid. However, the silk screen printing for a couple of GPIO pins is slightly hard to read. Otherwise, highly recommended for beginners.

Reliable and fast
I've bought five of these for my students. All of them work out of the box. The dual-core processor handles multitasking well for our sensor data logging project.
Q: Does this board support MicroPython?
A: Yes, this ESP32 development board is fully compatible with MicroPython. You can flash the firmware using esptool.py and start coding in Python immediately.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, you should not connect a LiPo battery directly to the 5V or 3.3V pins. Use the VIN pin which accepts a range of input voltages, or ensure you have a proper voltage regulator circuit between the battery and the board.
Q: What driver do I need for the CH340C chip on macOS?
A: For macOS, you typically need to install the CH340/CH341 serial driver. Most modern macOS versions may recognize it automatically, but if not, the driver is available on the manufacturer's website.
Q: Is the antenna external or internal?
A: This module features an onboard PCB antenna. It does not have a connector for an external antenna, but the internal antenna provides sufficient range for most indoor applications.
Q: How many PWM channels does this board support?
A: The ESP32 chip supports up to 16 independent PWM channels. You can configure the frequency, duty cycle, and bit resolution via software for various motor control or LED dimming tasks.
