Best bang for your buck
Compared to other development boards in this category, the feature set here is unbeatable. The integrated antenna works well, and the power consumption in deep sleep mode is very low.

Perfect for IoT prototyping
This board works flawlessly right out of the box. The Type-C connector is a huge plus, and the CH340 driver installed easily on my Windows machine. I got my first LED blink project running in minutes.

Reliable dual-core performance
I am using this for a home automation sensor node. The dual-core processor handles MQTT messaging and sensor reading simultaneously without any lag. Highly recommended for serious hobbyists.

Beginner friendly
As someone new to embedded systems, I found this board very easy to set up with the Arduino IDE. Plenty of tutorials available online specifically for this model. Great learning tool.

Great value, minor pin labeling issue
Excellent performance for the price. Wi-Fi range is impressive. The only downside is that some of the pin labels on the silkscreen are a bit small to read without a magnifier, but the documentation online is clear.

Solid hardware, runs hot under load
The build quality is good and the Type-C port feels durable. Note that it does get warm when using Wi-Fi and Bluetooth simultaneously at high transmission powers, but nothing concerning for normal use.
Q: Does this come with headers pre-soldered?
A: No, this board is shipped without headers soldered to give you the flexibility to choose between male, female, or no headers depending on your project needs. You will need to solder them yourself.
Q: How many PWM channels are available?
A: The ESP32 features 16 independent PWM channels that can be configured on almost any GPIO pin, allowing for complex motor control or LED dimming applications.
Q: Is the CH340 driver included in the latest macOS versions?
A: Recent versions of macOS often require manual installation of the CH340 driver. You can download the official driver from the WCH website or use a package manager like Homebrew to install it easily.
Q: Does this board support 5GHz Wi-Fi networks?
A: No, the ESP32 chip on this board only supports 2.4GHz Wi-Fi networks (802.11 b/g/n). It does not support 5GHz bands.
Q: Can I power this board directly from a 3.7V LiPo battery?
A: Yes, you can connect a 3.7V LiPo battery to the 5V and GND pins, as the onboard regulator can handle input voltages typically between 5V and 12V, but for direct 3.7V connection, please ensure you connect to the appropriate raw input pin if available or use the 5V pin which usually accepts a range down to 4.5V safely. For strict 3.7V, check the spec...
