Great 'thing'.but. good for single board computers

This works as advertised on the breadboard, but one thing I noticed is that the battery jack is wired backwards for most 3.7v LiPo batteries. I connected the battery before I noticed and smelled smoke. I hope I didn't burn it. battery or circuit board. Why do you connect it upside down to most LiPo batteries with JST connectors?

Pros
  • Rugged finish
Cons
  • Annoys

Lots of (fun) features, easy to use

As advertised, this little card is easy to use. All you need to get started is a micro USB cable and a laptop or desktop computer. I tried the wifi example program and it connected to my wifi network and then read the web page from "example.com" wherever it was with no problems. I think it will be very funny.

Pros
  • That's great
Cons
  • Expandable

Good ESP32 development environment.

I like Sparkfun. This is a good ESP32 development board. It's well documented. It works great with the Arduino and has some additional features on the board such as: B. a temperature sensor, an onboard button and an onboard LED. I was able to get SPI to work with a MicroSD card. Lots of program memory. for these great sketches. Soldering connectors is easy. I have several.

Pros
  • Worth the money
Cons
  • Everything great

Unreliable on computers and accessories

I have one and I'm giving it a bad rating because I also have 4 other ESP32 boards. My Sparkfun ESP32 thingy is very unreliable - it's having issues with Wi-Fi. Occasionally I can't reconnect. All other boards are built from ESP modules, this board only uses the ESP chip and has it's own layout, antenna etc, so I suspect that's the problem. In short, for $7-$10 you can buy a better ESP32. Board on Revain than this. I kind of wish I could use this because it had a battery connector that the…

Pros
  • Great for me
Cons
  • No instructions
