Solid performance, minor heat issue
Excellent development board for learning embedded systems. It gets slightly warm during heavy Wi-Fi usage, but nothing concerning. Documentation support is good.

Great starter kit component
I bought this for a university project. Setting up the Arduino IDE was straightforward, and the community support for ESP32 is huge. Highly recommended.

Good board, wish it had more RAM
For most projects, 520KB is enough, but if you are doing complex image processing, you might hit limits. Otherwise, it's a fantastic board.

Perfect for IoT Prototyping
This board works flawlessly out of the box. The Wi-Fi connection is stable, and the pinout is clearly labeled. Great value for money.
Q: Does this support external antennas?
A: This specific model (WROOM-32E) uses an onboard PCB antenna. If you require an external antenna, please look for models with an IPEX connector.
Q: Can I power this board with a battery?
A: Yes, you can power it via the 5V and GND pins using a Li-Ion battery with a proper voltage regulator, or directly via the VIN pin if your battery voltage matches the onboard regulator requirements (typically 5V input).
Q: Is this compatible with the Arduino IDE?
A: Yes, the ESP32-DevKitC is fully compatible with the Arduino IDE. You just need to install the ESP32 board manager package.
Q: What is the maximum current this board can supply to peripherals?
A: The 3.3V pin can typically supply up to 500mA, but we recommend keeping the load under 300mA for stability. The 5V pin passes through the USB input current minus the board's consumption.
Q: Does this board come with a USB cable included?
A: No, the USB cable is sold separately. You will need a standard Micro-USB or USB-C cable depending on the specific revision of the board you receive.
