Perfect for IoT Projects
This ESP-32 board is exactly what I needed for my home automation setup. The dual-core processing handles Wi-Fi and sensor data simultaneously without lag. Setup was straightforward using the Arduino IDE.

Solid performance for prototyping
We use these for rapid prototyping before moving to custom PCBs. They are reliable and the low power modes are genuinely useful for battery-operated prototypes. Wish it had a built-in battery connector.

Great value, minor documentation gaps
Hardware quality is excellent and the price is unbeatable. I deducted one star because the pinout diagram on the back is a bit small to read, but online resources filled the gap quickly.

Bluetooth works flawlessly
I bought this specifically for a BLE beacon project. Connection stability is impressive, and the range is better than expected for such a compact board. Highly recommended for beginners and pros alike.

Best bang for your buck
You simply cannot beat the features per dollar here. Wi-Fi, Bluetooth, plenty of IO, and fast processing. I've ordered five more for my next batch of projects.

Easy to get started
As someone new to embedded systems, I found this board very forgiving. Plenty of tutorials exist, and the community support is huge. It uploaded my first sketch on the first try.
Q: Does this board come with headers pre-soldered?
A: No, this version typically comes without headers soldered to allow for flexible mounting options. You will need to solder them yourself if required for your project.
Q: Is this compatible with the ESP-IDF framework?
A: Yes, this board is fully compatible with the Espressif ESP-IDF development framework, as well as Arduino IDE, MicroPython, and PlatformIO.
Q: Can I power this board via the micro-USB port?
A: Yes, you can power the board directly through the micro-USB port, which provides 5V. The onboard regulator converts this to the required 3.3V for the ESP32 chip.
Q: Does it support external antennas?
A: This specific model uses the onboard PCB antenna. If you require an external antenna for longer range, please look for our variant labeled 'ESP32 with External Antenna Connector'.
Q: What is the maximum current output 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 datasheet to avoid damaging the chip.
