Perfect for IoT Prototyping
This board is exactly what I needed for my home automation project. The Wi-Fi connection is stable, and the pinout is clearly labeled. Setup with the Arduino IDE was seamless.

Great value, minor heating
Excellent development board for the price. It handles dual-core tasks well. I noticed it gets slightly warm during heavy Wi-Fi transmission, but nothing concerning for a dev board.

Solid performance
Good board overall. The Bluetooth range is decent for indoor use. My only wish is that it came with headers pre-soldered, but that's a minor inconvenience.

Beginner Friendly
As someone new to embedded systems, this board was easy to get started with. Plenty of tutorials online specifically for the ESP32-DevKitC series. Highly recommended for learning.

Reliable for Student Projects
We bought ten of these for our university robotics club. They have been robust and consistent. The broken-out pins make breadboarding very convenient.

Exceeded Expectations
Using this for a remote environmental sensor node. The deep sleep modes work perfectly to save battery, and the wake-up timers are accurate. Very impressed.
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 GPIOs should not exceed the chip's maximum rating to avoid damage.
Q: Is this compatible with the Arduino IDE?
A: Yes, the ESP32-DevKitC-32E is fully compatible with the Arduino IDE. You simply need to install the ESP32 board manager package via the preferences menu.
Q: Can I power this board directly via the 5V pin?
A: It is recommended to power the board via the Micro-USB port or the VIN pin if using an external 5V supply. Directly feeding 5V into the 3.3V pin will damage the board.
Q: Does this support Over-The-Air (OTA) updates?
A: Yes, the ESP32-WROOM module supports OTA updates, allowing you to upload new firmware wirelessly once the initial connection is established.
Q: Does this board come with headers pre-soldered?
A: No, this module typically comes without headers soldered to allow for flexible mounting options. You will need to solder your own headers if you plan to use it on a breadboard.
