Exceeded expectations
The range on the Wi-Fi antenna is surprisingly good compared to other boards in this price range. Deep sleep mode also works as advertised, saving battery life significantly.

Reliable for classroom use
We bought ten of these for our workshop. Nine worked perfectly out of the box; one had a slightly loose USB port but still functions. Great bulk purchase overall.

Best board for learning embedded systems
As a university student, this was the perfect choice for my final year project. Flashing new firmware is quick, and the 4MB flash gives plenty of room for complex scripts.

Great value, minor pin labeling issue
The performance is excellent for the price. My only complaint is that some of the GPIO pin labels on the silkscreen are a bit small to read without a magnifier. Otherwise, it's a solid board.

Dual Core Powerhouse
I am using this for a home automation project involving multiple sensors. The dual-core processor handles the load effortlessly, and the Bluetooth Low Energy feature is a nice bonus.
Q: What is the maximum current draw per GPIO pin?
A: Each GPIO pin can source or sink up to 40mA. However, the total current drawn from all pins combined should not exceed specific limits outlined in the datasheet to avoid damaging the chip.
Q: Can I program this using the Arduino IDE?
A: Absolutely. The ESP32 is fully compatible with the Arduino IDE after installing the ESP32 board manager package.
Q: Does this support external antennas?
A: This specific revision (V1.0.0 Rev1) uses an onboard PCB antenna. It does not have a connector for an external antenna.
Q: Is the CP2102 driver pre-installed on Windows 10?
A: Windows 10 usually installs the driver automatically upon connection. If not, you can easily download the official SILABS CP210x drivers from their website.
Q: Does this board come with a USB cable included?
A: Yes, the package includes a standard micro-USB cable for power and data transfer.
