Solid performance for robotics
Using this to control a small rover. The PWM outputs are precise, and the Bluetooth range is sufficient for indoor control. Would give 5 stars if it came with header pins pre-soldered.

Best bang for your buck
I've tried several development boards, and this one offers the best features for the price. The built-in antenna works well, and the power consumption is impressively low in deep sleep mode.

Great value, minor pin labeling issue
Excellent performance and stable Bluetooth connection. My only complaint is that some of the GPIO pin labels on the silkscreen are slightly hard to read under low light. Otherwise, a solid board.

Low power consumption verified
Tested the deep sleep current draw, and it matches the datasheet specs perfectly. Ideal for battery-powered environmental monitoring stations. Very happy with this purchase.

Perfect for IoT Prototyping
This ESP32 board is exactly what I needed for my smart home project. The dual-core processing handles WiFi and sensor data simultaneously without lag. Setup with Arduino IDE was seamless.
Q: Can I power this board directly via the 5V pin?
A: Yes, you can supply 5V to the VIN or 5V pin. The onboard regulator will step it down to 3.3V for the ESP32 chip. Ensure your power source is stable.
Q: Does this board come with pre-soldered header pins?
A: No, this board typically comes without header pins soldered to allow for flexible mounting options. You will need to solder them yourself or use jumper wires directly.
Q: Does the Bluetooth support both Classic and BLE?
A: Yes, the ESP32 supports both Bluetooth Classic (BR/EDR) and Bluetooth Low Energy (BLE), making it versatile for various audio and data transmission applications.
Q: Is this compatible with the Arduino IDE?
A: Yes, the ESP-32 is fully compatible with the Arduino IDE. You just need to install the ESP32 board manager package following the standard setup instructions.
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 drawn from all pins combined should not exceed the chip's maximum rating to avoid damage.
