Bought ten for our lab
We equipped our entire student workstation with these. They have held up well to frequent plugging and unplugging. Highly recommended for educational settings.

Stable power delivery
I've been running a Wi-Fi heavy application for 48 hours straight on this board. No voltage drops or resets. The AMS1117 regulator handles the load well.

Essential for beginners
If you are just starting with ESP32, get this. It saves so much time wiring up power supplies. The onboard LED is bright enough to see status clearly.

Solid construction
The PCB feels sturdy and the traces look thick enough for current draw. Deducted one star because the silkscreen labeling is a bit small, but readable with a magnifier.

Good value, minor spacing issue
Overall a great expansion board. The voltage regulation is stable. I noticed the mounting holes are slightly tight for standard M3 screws, but nothing a little filing couldn't fix.

Perfect fit for my ESP32 projects
This board fits the ESP32S perfectly. The pin alignment is spot on, and the soldering quality looks professional. It made powering my sensor array much easier without needing a breadboard.
Q: Does it come with stacking headers included?
A: The board comes with the male headers pre-soldered. Stacking female headers are not included but can be purchased separately.
Q: Does this board support the original ESP32 DevKit V1?
A: Yes, the 38-pin header layout is designed to be compatible with both the ESP32 and ESP32S DevKit modules.
Q: Can I power this board via the VIN pin instead of USB?
A: Absolutely. You can supply 5V directly to the VIN pin if you prefer not to use the Micro-USB port.
Q: What is the maximum current output of the 3.3V regulator?
A: The onboard AMS1117 regulator can typically supply up to 800mA, though we recommend staying under 500mA for optimal thermal performance.
Q: Are the GPIO pins broken out individually?
A: Yes, all relevant GPIO pins from the ESP32 module are broken out to the header pins for easy access with jumper wires.
