High performance esp32 module; Small volume, easily embeded to other products; Supporting Lua program, easily to develop. Reference links of ESP32 at below: https://github.com/Nicholas3388/LuaNode ; https://github.com/nodemcu/nodemcu-firmware/tree/dev-esp32 Package included: 3 X ESP-32 unassembled development board 6 X 15 pins header Tips: When you download the program to ESP32, you need to press the IOO button for 1-2 seconds. When you open your Arduino IDE Serial monitor and the error message “Brownout detector was triggered” is constantly being printed over and over again. It means that there’s some sort of hardware problem. It’s often related to one of the following issues: Poor quality USB cable; USB cable is too long; Board with some defect (bad solder joints); Bad computer USB port; Or not enough power provided by the computer USB port.
