Reliable and Fast
Using it to control my smart home sensors. The dual-core processor handles multiple tasks without lag. Highly recommend for automation projects.

Best ESP32 board I've used
Compared to other generic boards, this one has better build quality and consistent performance. The 4MB flash is plenty for most scripts.

Solid hardware, good pins layout
The pinout is clearly labeled which saves time during wiring. Power consumption is reasonable in deep sleep mode. Would buy again.

Easy to get started
I was worried about the setup, but flashing MicroPython took less than 5 minutes. The community support is amazing.

Perfect for IoT Prototyping
This board works flawlessly with MicroPython. The Wi-Fi connection is stable, and the Bluetooth pairing was instant. Great value for the price.

Great learning tool
Bought this for my university project. Documentation is abundant online. Only minor issue is the USB cable included felt a bit flimsy, but the board itself is solid.
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 for all IO ports combined should not exceed specific limits outlined in the ESP32 datasheet to avoid damaging the chip.
Q: How do I enter boot mode?
A: To enter boot mode, hold down the 'BOOT' button while pressing the 'RESET' button. Release the 'RESET' button first, then release the 'BOOT' button after a second.
Q: Is the antenna external or internal?
A: This model features an onboard PCB antenna. There is no connector for an external antenna on this specific revision.
Q: Can I power this directly from a 9V battery?
A: While the VIN pin accepts a range of voltages, we recommend using a 5V source via the Micro USB port or a regulated 5V input for stability. A 9V battery may work but could cause overheating if not regulated properly before reaching the board.
Q: Does this board support the Arduino IDE?
A: Yes, this ESP32 board is fully compatible with the Arduino IDE. You just need to install the ESP32 board manager package.
