This breakout board can expand one GPIO pin of esp32 development board to two, which is convenient for users to reuse all pins in smart home projects. Nice breadboard alternative. Review: Works, reliable, flashes with no button pressing (on linux) - I got these to replace some nearly identical ones from a different seller which had super flaky wifi (it turned out due to counterfeit USB chip leaking high voltage to the ESP32). I'm happy to report that, despite having a no-name USB chip (CP2102 clone, I think) all the voltages measure as they should (unlike the other brand) and the units work so far flawlessly. I bought these from KeeYees this time because I had purchased some ESP8266s from them a long time ago which have worked great for years, and so far it looks like their ESP32s are similarly well-enough made. So, if you are scratching your head over which brand of this board to buy when there seem to be so many that are exactly the same: Beware they may be the same design but the components matter, and so far for me at least KeeYees has sent me good, working boards, spanning multiple years, which I can't say for some other random brands/sellers. Review: Great with WLED - I used one of these programmed with WLED software to run 12V LEDs on my Christmas tree. It was a big project since you need a 12V power supply, a voltage converter (to get the 5v this device needs) and a box to connect multiple strings of lights into a central hub. Worth it. In the video, you might notice the star is doing its own thing. It's got another one of these microcontrollers wired up to a dozen white LEDs with some custom code (not WLED). That one runs off a USB plug which is a lot simpler. ## Features - This 30-pin version of the ESP32 board has 4 mounting holes, which will be very convenient for you to fix it when some projects need it. - This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips ESP-WROOM-32, as well as the 40nm low-power technology. - Support Lua program, easy to develop. Support of three modes: AP, STA and AP + STA. - This module is safe, reliable, and scalable to a variety of applications. - Technical Support: Our PDF tutorial is available on this page.

The pinout is wrong on this board so finding support for projects is nearly impossible. **Q: Where is a schematic? need to understand why some gpio pins don't work as expected. p0 and p19 don't work, p2 works but has an on-board blue led.** A: The PCB's silkscreen gpio is labeled different from the physical on-board gpio of the chip. **Q: Has anyone had any luck getting micropython onto this board?** A: Yes.
