Review on SparkFun ESP32 Thing Development Board: Wireless IoT Prototyping with Bluetooth, Integrated LiPo Battery Charger & 4MB Flash Memory by Liam Roth

Revainrating 3 out of 5

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
